jin.2andhyunjinee 9f51879012 fix: rewrite getByRole to use CDP accessibility tree with ref-based element resolution (#1145)
* fix: rewrite getByRole to use CDP accessibility tree instead of CSS selectors

The old `handle_getbyrole` generated `querySelectorAll('[role="link"], link')`
which matched `<link>` stylesheet elements instead of `<a>` anchor tags.
This happened because ARIA role names were used directly as CSS tag selectors,
and several roles differ from their HTML element names (e.g. link → a,
heading → h1-h6, textbox → input/textarea).

The fix replaces the JS-based DOM query with the CDP `Accessibility.getFullAXTree`
API, where the browser engine correctly computes implicit ARIA roles per the
WAI-ARIA / HTML-AAM spec. This is the same approach already used by `snapshot.rs`
and `element.rs` in this codebase.

Changes:
- Rewrite `handle_getbyrole` to query the browser's accessibility tree via CDP
- Add `find_ax_node_by_role` helper for AX tree traversal with role/name/exact matching
- Use `DOM.resolveNode` + `Runtime.callFunctionOn` to bridge AX node → DOM marker
- Add iframe support via `resolve_ax_session` (missing in old implementation)
- Fix cleanup to use correct CDP session (old code used default session, breaking iframe cleanup)
- Export `extract_ax_string` as `pub(super)` for reuse
- Add 4 regression tests for `find_ax_node_by_role`

Fixes #1123

* style: apply cargo fmt

* chore: remove redundant comments

* refactor: replace marker attribute with temporary ref for element resolution

Eliminates 3 CDP round-trips (DOM.resolveNode, Runtime.callFunctionOn,
Runtime.evaluate cleanup) by registering a temporary ref in the ref_map.
execute_subaction resolves the element via backendNodeId directly.
No more DOM pollution with marker attributes.

* fix: ref counter collision, ref_map leak, and stale fallback name

- Increment next_ref_num after inserting temp ref to prevent id collision
- Remove temp ref after execute_subaction to prevent unbounded ref_map growth
- Return actual AX name from find_ax_node_by_role for accurate fallback resolution
- Add RefMap::remove method

jin.2andhyunjinee 59b6e5a034 feat: support cross-origin iframe snapshots and interactions via Target.setAutoAttach (#949)
* feat: support cross-origin iframe snapshots and interactions via Target.setAutoAttach (#925)

Enable Target.setAutoAttach with flatten: true on page sessions so Chrome
auto-creates dedicated CDP sessions for cross-origin iframe targets.

- Add DrainedEvents struct, iframe_sessions map, attach/detach event handling
- Extract resolve_ax_session (shared) and resolve_frame_session helpers
- resolve_element_object_id returns (object_id, effective_session) tuple
- resolve_element_center returns (x, y, effective_session) tuple
- Input dispatch (click/hover/tap) uses effective session for correct coordinates
- Thread iframe_sessions through element.rs, interaction.rs, screenshot.rs
- Clear iframe sessions on navigate, tab switch, tab new, tab close
- Ignore Target.setAutoAttach failure for non-Chrome backends (Lightpanda)
- Unit tests for session resolution logic

jin.2andhyunjinee af800f8403 fix: support xpath= selector prefix in element resolution (#908)
* fix: support xpath= selector prefix in element resolution

Resolves #907. When a selector starts with "xpath=", use
document.evaluate() instead of document.querySelector() so that
XPath expressions like "xpath=//button" work correctly.

* test: replace overlapping test with edge case tests

Replace test_build_selector_js_xpath_strips_prefix (which overlapped
with the xpath test) with two edge case tests: empty xpath and
selector starting with "xpath" without "=" delimiter.

* fix: support xpath= selector in resolve_element_object_id

Apply the same xpath= handling to resolve_element_object_id, which is
used by type, fill, focus, hover, check, select, screenshot, drag,
and all other selector-based commands beyond basic click.

* refactor: extract build_find_element_js to deduplicate xpath/css logic

The xpath= vs querySelector branching was duplicated in both
build_selector_js and resolve_element_object_id. Extract the shared
logic into build_find_element_js and reuse it in both places.

* fix: support xpath= selector in get_element_count

Use ORDERED_NODE_SNAPSHOT_TYPE with snapshotLength for XPath counting,
matching the querySelectorAll().length behavior for CSS selectors.

* refactor: rename find to find_expr for clarity

* refactor: extract build_count_elements_js and add regression tests

Extract element counting JS generation into build_count_elements_js
helper (matching the pattern of build_find_element_js) and add tests
for both CSS and XPath counting paths.

Chris Tateandctate 60f3afcf61 Add iframe support for CLI interactions and snapshots (#869)
* Add iframe support for CLI interactions and snapshots

This PR adds comprehensive iframe support to the agent browser CLI, allowing users to interact with elements inside iframes seamlessly.

## Problem
Users couldn't interact with elements inside iframes via the command line. The existing `frame` command was non-functional as it set `active_frame_id` but no other code read this value.

## Changes Made

### Enhanced Frame Context Tracking
- Added `frame_id` field to `RefEntry` to track which frame each element reference belongs to
- Updated `RefMap::add` and related methods to accept and store frame context
- Modified element resolution functions to use frame context from ref entries

### Improved Frame Command
- Fixed the existing `frame` command to actually work by threading `active_frame_id` through snapshot operations
- Added support for iframe element references (e.g., `frame @e2`) in addition to CSS selectors
- Enhanced frame detection to work with both named frames and iframe elements

### Updated Snapshot Behavior
- Modified `take_snapshot` to accept optional frame context parameter
- Updated all snapshot call sites to pass appropriate frame context
- Maintained backward compatibility while enabling frame-scoped operations

### Element Resolution Updates
- Updated `resolve_element_center` and `resolve_element_object_id` to use frame context from ref entries
- Modified `find_node_id_by_role_name` to support frame-specific element lookup
- Ensured all interaction functions work correctly within iframe contexts

## Implementation Details
- Frame context is now properly propagated through the entire element interaction pipeline
- The `frame` command can accept both CSS selectors and element references
- All existing functionality remains intact while adding iframe capabilities
- Added `Iframe` to interactive roles for better element discovery

Fixes #863

* docs: add iframe support documentation

Document the new iframe capabilities across all documentation surfaces:
- Auto-inlining of iframe content in snapshots
- Direct interaction with iframe element refs
- frame command support for element refs (@e3)
- Scoped snapshots via frame switching

* fix: pass active frame context to diff snapshots and fix nameless iframe lookup

- handle_diff_snapshot now respects active_frame_id instead of always
  passing None, so diff snapshots work correctly inside iframes
- Nameless/id-less iframes now fall back to src URL (or null) instead of
  the literal string 'frame' which never matched any frame in the tree

* fix: resolve iframe frame ID via DOM.describeNode and reduce code duplication

- handle_frame: Use DOM.describeNode + contentDocument.frameId to resolve
  iframe frame IDs directly, fixing failures for nameless iframes that
  lack name/id/src attributes
- element.rs: Deduplicate add() by delegating to add_with_frame()
- snapshot.rs: Guard against out-of-bounds insert_str when iframe marker
  is on the last line without a trailing newline

Chris Tateandctate 8ac7fe916e fix: restore Playwright-parity check/uncheck for Material Design controls (#837)
The v0.20.0 migration from Playwright to the native Rust daemon introduced
two regressions in checkbox/radio handling:

1. `is_element_checked` only read `this.checked`, which is undefined on
   non-input elements. Material Design and ARIA controls use wrapper divs
   with `role="checkbox"` and `aria-checked`, or hide the native input
   off-screen inside a label. The function now mirrors Playwright's
   `getChecked()` with follow-label retargeting: native `.checked`,
   `aria-checked` for ARIA roles, `label.control` traversal, and nested
   input lookup.

2. `check`/`uncheck` accepted the coordinate-based CDP click result
   without verifying the state actually changed. When the AX tree's
   `backendDOMNodeId` points to a hidden off-screen input (common in
   Material Design), `Input.dispatchMouseEvent` hits nothing. The actions
   now re-check state after clicking and fall back to a JS `.click()` on
   the resolved input — matching Playwright's `_setChecked` verify step.

Adds e2e regression test covering Material Design (hidden input + ripple
overlay), ARIA-only, and native checkbox patterns.

Chris Tateandctate c07f43e242 fix: re-query accessibility tree when backend_node_id is stale (#806)
* fix: gracefully fall back to role/name lookup when backend_node_id is stale

When the DOM changes between snapshot and click (common with SPAs and
dynamic UIs), the stored backend_node_id becomes invalid. Previously,
DOM.getBoxModel and DOM.resolveNode failures propagated as hard errors,
bypassing the role/name fallback path entirely. Now these failures are
caught and the code falls through to a JS-based element lookup.

Also adds resolve_object_id_by_role_name so that resolve_element_object_id
has a fallback for ref-based lookups (previously it had none), and
improves the role matching JS to correctly map implicit ARIA roles
(e.g. <input type="submit"> → "button", <a href> → "link").

Closes #805

* test: add e2e regression test for stale ref click fallback (#805)

Verifies that clicking a ref whose backend_node_id has become stale
(because the DOM was replaced by JavaScript) falls back to role/name
lookup instead of failing with "Could not compute box model".

* fix: use accessibility tree for stale ref fallback instead of JS heuristic

Replace the hand-rolled JS role/name matching (getImplicitRole,
getAccessibleName) with a re-query of Accessibility.getFullAXTree —
the same data source that built the ref map during snapshot. This
guarantees role/name matching is identical to what was stored,
preventing silent wrong-element clicks from name computation
divergence (e.g. aria-labelledby, <label for>, alt text).

Matches v0.19.0 (Playwright) behavior where getByRole always
re-queried the live accessibility tree.
