chore(release): bump to 0.27.0-fork.16 — click reliability (scroll-into-view + DOM fallback) + skill docs (console opt-in, CLICK_MODE, form/hidden-input eval)

fix(click): scroll into view + DOM-dispatch fallback for reliable clicks
Real-world dogfooding surfaced clicks that resolve a valid @ref but still miss: - Scroll the target into view before computing click coordinates (scrollIntoViewIfNeeded). Without it, an element below the fold — or revealed after a scroll/popup — yields off-viewport coordinates and the click lands on whatever occupies that screen point. - Fall back to a DOM-dispatched `.click()` when the coordinate path fails (a persistent floating layer failing the occlusion guard, or coordinates that won't resolve). The DOM dispatch targets the intended element directly instead of a screen point, so an overlay or portal can't divert it. - AGENT_BROWSER_CLICK_MODE: "" (default: scroll + coordinate + DOM fallback), "coord" (strict coordinate, hard-fail on occlusion), "dom" (always element.click() — best for autocomplete/menu <li> that close on input blur). Fallback is limited to left single-clicks (DOM .click() can't express right/middle/double). Non-left/multi and "coord" mode keep the original error. Docs: README knob table + skill commands.md gain CLICK_MODE, a click-reliability note, and a "debug forms/hidden inputs with eval" section (snapshot doesn't show hidden inputs — the fast path to bugs like a hidden point_choice=none). 6 click/interaction e2e green; full suite 760 passed.

+- **Pin a version:** `AGENT_BROWSER_VERSION=v0.27.0-fork.12 curl -fsSL https://raw.githubusercontent.com/leeguooooo/agent-browser-stealth/main/install.sh | sh`
+- **Custom location:** `AGENT_BROWSER_BIN_DIR=$HOME/bin curl -fsSL … | sh`
+- **Windows:** download `agent-browser-win32-x64.tar.gz` from the [Releases page](https://github.com/leeguooooo/agent-browser-stealth/releases) and put `agent-browser.exe` on your PATH.

 This drops `skills/agent-browser` (and the specialized `skill-data/{core,electron,slack,dogfood,agentcore,vercel-sandbox}`) into your project so your AI agent gets the right usage patterns and pre-approved bash permissions for `agent-browser`, `agent-browser-stealth`, and `abs`.

+`agent-browser`, `agent-browser-stealth`, and `abs` are **the same binary** —
+`abs` is just a short alias. There is no separate "stealth executable"; stealth
+is a runtime behavior (see [Anti-detection](#anti-detection) below), applied
+automatically based on whether you attach to your real Chrome or `--launch` a
+fresh one.

-1. Open `chrome://inspect/#remote-debugging` in Chrome
-2. Toggle the switch on
+## Setup: connect to your Chrome

-That's it. This setting persists across Chrome restarts.
+Attaching uses the Chrome DevTools Protocol, which Chrome only exposes when it is
+**launched with a remote-debugging port**. This is a startup flag, not a setting
+— the `chrome://inspect` toggle alone is **not** enough (it only enables target
+discovery, not the CDP attach).
+
+**Recommended — fully quit Chrome, then relaunch with the port:**
+
+```bash
+# macOS
+open -a "Google Chrome" --args --remote-debugging-port=9222
+# Linux
+google-chrome --remote-debugging-port=9222
+# Windows: add --remote-debugging-port=9222 to your Chrome shortcut's target
+```
+
+Then run `agent-browser open <url>` — it auto-discovers the port and attaches.
+On first attach, **Chrome 136+ shows an "Allow remote debugging?" dialog — click
+Allow once** (it persists for that Chrome session).
+
+**No setup / don't want to touch your real Chrome?** Use
+`agent-browser --launch open <url>` to spawn a fresh isolated stealth browser
+(full anti-detection patches applied; see below). This always works without any
+port setup and is what CI uses automatically.

-If you need a separate browser (CI, testing, etc.):
+Spawn a separate browser instead of attaching to your running Chrome:

 ```bash
+# Throwaway: fresh, EMPTY profile — no cookies, no login (good for CI/testing)
 agent-browser --launch open https://example.com
+
+# Keep your login: launch with your real Chrome profile (cookies/sessions intact)
+agent-browser --launch --profile auto open https://x.com/home
+# or name it explicitly: --profile Default / --profile "Profile 1"
 ```

+> ⚠️ Plain `--launch` (no `--profile`) uses a **temporary empty profile** — you will
+> NOT be logged into anything. For logged-in sites use `--profile auto` (picks the

+### Tuning knobs (environment variables)
+
+| Variable | Default | Effect |
+|---|---|---|
+| `AGENT_BROWSER_CAPTURE_CONSOLE` | off | Enable `Runtime` domain so `console` / `errors` capture page output. Off keeps the stealthiest profile. |
+| `AGENT_BROWSER_TIMEZONE` | unset | `--launch` only. An IANA id (e.g. `Asia/Tokyo`) sets the timezone natively (Intl + Date follow, no JS lie) to match a proxy; `auto` derives one from the locale. |
+| `AGENT_BROWSER_BLOCK_WEBRTC` | auto | `--launch` only. Auto-forces WebRTC through the proxy when one is set (no real-IP leak). `1` hides the local IP without a proxy; `0` opts out. |
+| `AGENT_BROWSER_HIDE_CANVAS` | off | `--launch` only. Adds session-stable canvas/audio fingerprint noise. Off by default (noise is itself a "lie"). |
+| `AGENT_BROWSER_ADAPTIVE_REF` | on | When a saved `@ref` moves and the role/name re-query fails, relocate it by fingerprint similarity (high score + clear margin required, else it fails loudly). `0` disables. |
+| `AGENT_BROWSER_CLICK_MODE` | _(auto)_ | Click strategy. Default scrolls the target into view, dispatches a coordinate click, and falls back to a DOM `.click()` if a floating layer occludes the point. `dom` always uses `.click()` (best for autocomplete/menu items that close on blur); `coord` is strict coordinate-only (hard-fail on occlusion). |

+### Debugging forms / hidden state with `eval`
+
+The a11y `snapshot` shows visible, interactive elements — it does **not** show
+hidden inputs or a control's actual submitted value. When a form "looks filled"
+but submit-validation rejects it, go straight to the DOM with `eval` instead of
+guessing from the snapshot. This is usually the fastest way to find the real
+problem (e.g. a hidden `point_choice=none` that the visible UI never exposes):
+
+```bash
+# Dump every field's name → value, including hidden inputs and unchecked radios
+agent-browser eval "JSON.stringify([...document.forms[0].elements].map(e=>({name:e.name,type:e.type,value:e.value,checked:e.checked})).filter(e=>e.name))"
+
+# Inspect one hidden field directly
+agent-browser eval "document.querySelector('[name=point_choice]')?.value"
+
+# Why won't it submit? Ask the browser's own validity API
+agent-browser eval "[...document.forms[0].elements].filter(e=>!e.validity?.valid).map(e=>e.name+': '+e.validationMessage)"
+```

+
+### Click reliability
+
+`click` auto-scrolls the target into view first, then dispatches a coordinate
+click. If that fails (a floating layer fails the occlusion guard, or the point
+won't resolve) it falls back to a DOM-dispatched `.click()` on the intended
+element. If a click *reports success but the page didn't react* — common for
+autocomplete/menu `<li>` items that close on the input's blur — retry that one
+with `AGENT_BROWSER_CLICK_MODE=dom` (a DOM dispatch doesn't move focus the way a
+real pointer press does, so the item still selects). `=coord` disables the
+fallback when you specifically want a hard failure on occlusion.
