* fix: restore WebSocket streaming in native daemon
The v0.20.0 Rust rewrite broke WebSocket streaming — connections opened
but received zero messages before closing. Multiple issues contributed:
1. StreamServer was dropped immediately after creation in daemon.rs,
closing the broadcast channel and killing all WS connections.
2. Screencast frames were only processed during command polling
(drain_cdp_events) instead of in real-time, unlike the 0.19.0
TypeScript cdp.on('Page.screencastFrame') callback.
3. Auto-start/stop screencast on WS client connect/disconnect was
missing from the Rust implementation.
4. Screencast CDP commands used the wrong session ID (daemon session
name instead of the CDP page session from Target.attachToTarget).
5. Broadcast channel Lagged errors killed WS connections instead of
being handled gracefully.
The fix adds a background CDP event loop in StreamServer that subscribes
to Chrome events and broadcasts screencast frames in real-time, properly
tracks the CDP page session ID, restores auto-screencast lifecycle, and
keeps the StreamServer alive in DaemonState.
Fixes#820
* fix: use actual CDP session ID for input dispatch in stream WebSocket
Pass the real cdp_session_id (from Target.attachToTarget) through to
handle_ws_client instead of an empty string. Previously, input commands
(mouse, keyboard, touch) were sent with `"sessionId": ""` which Chrome
silently rejects. Now the correct page session ID is read at dispatch
time, and when no session ID is set yet (before browser launch),
the field is omitted entirely via `None` so Chrome uses browser-level
dispatch.

* fix: snapshot --selector scopes to the matched element subtree
The native Rust daemon accepted the --selector flag but never used it —
the full accessibility tree was always returned regardless of the
selector. This restores the 0.19.0 behaviour where snapshot --selector
returns only the subtree rooted at the matched CSS selector.
The implementation resolves the selector via Runtime.evaluate, fetches
the full DOM subtree with DOM.describeNode(depth: -1) to collect all
descendant backendNodeIds, then filters the AX tree to render only the
nodes whose backendDOMNodeId falls within that set. This correctly
handles elements like <body> that don't map to a direct AX node.
Also fixes handle_snapshot reading "depth" instead of "maxDepth" from
the command JSON, which caused --depth to be silently ignored.
Fixes#822

* fix: replace screenshot polling with screencast-based piped ffmpeg recording
Recording previously used Page.captureScreenshot polling at 10fps,
which was CPU-heavy and produced inconsistent results. Now uses
Page.startScreencast with throttled acks (35ms interval) to receive
frames event-driven from Chrome, and pipes JPEG data directly to
ffmpeg stdin in real-time instead of saving temp files.
- Spawn ffmpeg at recording start with piped stdin (image2pipe)
- Background task receives screencast frames, interpolates gaps by
repeating the last frame based on timestamps, targets 25fps
- Ack throttling controls Chrome's frame push rate
- Fix: current frame was never written after the first one
- Fix: frame count was read before task finished padding
- Remove tokio-util dependency (replaced CancellationToken with oneshot)
- Add tokio "process" feature for async child process stdin pipe
- Extract start/stop_recording_task helpers on DaemonState
- Add tests for restart, ffmpeg codec selection, and stop without task
* fmt
* chore
* fix: switch WebM codec from VP9 to VP8 for correct framerate and browser
compatibility
VP9 realtime encoder ignored input framerate, producing 10fps output
instead of 25fps. This caused inconsistent playback in browsers.
VP8 respects -framerate 25 and has wider browser playback support.
* fmt
* fix: add kill_on_drop to ffmpeg process to prevent zombie on task panic
* fix: switch from screencast to screenshot polling for reliable recording duration
Screencast only pushes frames on visual changes, producing short videos
on static pages. Screenshot polling captures at a fixed 10fps interval
regardless of page activity, guaranteeing duration matches wall-clock time.
ffmpeg piped stdin architecture is preserved — no temp files.

Replace all `eprintln!` calls in daemon-context code with
`let _ = writeln!(std::io::stderr(), ...)` so that broken pipe errors
on stderr are silently ignored instead of panicking.
The CLI client spawns the daemon with piped stderr to capture startup
errors, then drops the pipe handle once the daemon is ready. Any
subsequent `eprintln!` in the daemon panics because Rust's `eprintln!`
macro internally unwraps the write result. This caused the reported
"failed printing to stderr: Broken pipe (os error 32)" panic during
Chrome launch on Linux.
Closes#799

The CDP event broadcast channel (capacity 256) can overflow on slow CI
runners when Chrome emits many events during navigation. Previously,
RecvError::Lagged was treated the same as RecvError::Closed, causing
spurious "Event stream closed" errors even though Chrome was still
running. Now all 5 event-receiving loops correctly continue on Lagged
instead of breaking.
- Restore the `refs` dictionary in `--json` snapshot output, matching the documented API contract
- The `refs` field was silently dropped during the Node.js to Rust rewrite (v0.20), causing consumers parsing `data.refs` for programmatic element interaction to receive no structured ref data
Fixes#785
The test was reading AGENT_BROWSER_HEADED without holding ENV_MUTEX,
causing a race with test_launch_options_from_env_headed_flag when
tests run in parallel.
* feat: add screenshot output config, clipboard CLI commands, and fix wait --text native path
## Summary
- Add `--screenshot-dir`, `--screenshot-quality`, and `--screenshot-format` CLI flags (with corresponding `AGENT_BROWSER_SCREENSHOT_DIR`, `AGENT_BROWSER_SCREENSHOT_QUALITY`, `AGENT_BROWSER_SCREENSHOT_FORMAT` env vars) so users can configure where and how screenshots are saved without specifying a full path every time
- Add `clipboard read`, `clipboard write <text>`, `clipboard copy`, and `clipboard paste` CLI commands, exposing the existing protocol-level clipboard handlers that were previously only accessible via JSON-RPC
- Fix `wait --text` in native mode: the CLI was emitting `selector: "text=..."` (a Playwright-style locator) which native's `querySelector` can't handle. Now emits a `text` field that correctly hits the native `wait_for_text` polling path
- Add native clipboard `copy` and `paste` support via CDP `Input.dispatchKeyEvent`, and a `write` operation to the Node.js handler
* fix: resolve CI failures in Rust formatting and TypeScript typecheck
Use string-based page.evaluate for clipboard writeText to avoid
referencing `navigator` in Node.js compilation context. Run cargo fmt
to fix formatting in commands.rs and screenshot.rs.
* fix: clipboard write captures full multi-word text
Use rest[1..].join(" ") instead of rest.get(1) so unquoted multi-word
input like `clipboard write hello world` sends the full string rather
than silently dropping everything after the first word.

TypeScript CI has prettier --check but Rust CI only runs cargo test.
Add cargo fmt --check to catch formatting issues early, and fix the
8 pre-existing formatting violations on main.
