* feat(emulate): add mobile device emulation via CDP Emulation domain
Add `bsk emulate` so agents can debug mobile page behaviour by
emulating a device environment on a session tab:
- Viewport metrics (Emulation.setDeviceMetricsOverride), User-Agent
(Emulation.setUserAgentOverride, optional accept-language and UA
client-hints metadata), and touch (Emulation.setTouchEmulationEnabled
with maxTouchPoints).
- Seven CLI-side device presets (iphone-14, iphone-14-pro-max,
iphone-se, pixel-7, galaxy-s23, ipad-mini, galaxy-tab-s8) via
--device; manual flags (--width/--height/--dpr/--mobile/--ua/
--accept-language/--touch/--max-touch-points) work standalone or
override individual preset fields.
- `bsk emulate --off` clears every override (clearDeviceMetricsOverride
+ touch disabled + empty UA override) and restores the real
environment.
- Overrides are per-tab (CDP per-target) and not inherited by new tabs;
the result JSON carries a note reminding agents to re-apply.
Wire: new tool.emulate method end-to-end (bsk-protocol types + JSON
schemas + Method::ToolEmulate classified BrowserMutation, daemon
forwarding, CLI subcommand, extension tool handler + ChromiumCdp
Emulation wrappers, dispatcher registration), docs in both SKILL.md
copies, and unit tests on every layer.
* refine(emulate): merge per-tab state and align preset override semantics
- extension: remember the applied emulation state per tab and merge each new request onto it field by field before applying, so a later --width/--height no longer resets an earlier preset's dpr/mobile; --off clears the stored state along with the CDP overrides
- extension: cdp_failed errors now note that already-applied overrides were not rolled back and can be reset with --off
- cli: validate width/height pairing and metric requirements on the merged preset+flags result, so --device iphone-14 --width 500 keeps the preset height
- cli: add --no-mobile/--no-touch (conflicting with --mobile/--touch) to turn preset mobile/touch fields back off
- docs: describe the merge behaviour, --no-mobile/--no-touch and --off state clearing in both SKILL.md copies
- `bsk session start --width <px> --height <px>` opens the Agent Window
with the given outer size (chrome.windows.create)
- new `bsk window resize --session <id> --width <px> --height <px>`
resizes the Agent Window at runtime (chrome.windows.update)
- both validated on CLI, daemon and extension sides (100..=7680 CSS px)
- protocol: new tool.window_resize method (BrowserMutation) and
optional width/height on tool.session_start params; schemas regenerated
* feat(request-help): add BSK_REQUEST_HELP=off to disable blocking help requests
* style(extension): format HelpOutcome union per biome
* docs(skill): condense BSK_REQUEST_HELP section
`enableConsoleDomains` marked the tab in `consoleDomainsAttemptedTabs`
before issuing `Runtime.enable`/`Log.enable` and swallowed any errors,
so a transient failure (e.g. a restricted page during attach)
permanently disabled console capture for that tab: every later
`ensureConsoleCapture` was a no-op and the agent silently got an empty
console buffer with no indication that capture was broken.
This was inconsistent with `enableNetworkDomain`, which records the tab
only after `Network.enable` succeeds (and is explicitly tested as
"retries and surfaces failures"). Bring `enableConsoleDomains` in line:
mark the tab only after both domains enable successfully, so a later
`ensureConsoleCapture` can recover from a transient failure. Renamed
the flag `consoleDomainsAttemptedTabs` -> `consoleDomainsEnabledTabs`
to match `networkDomainsEnabledTabs` and reflect the new semantics.
Attach remains best-effort (it still succeeds when a domain can't be
enabled). Adds a regression test asserting `ensureConsoleCapture`
retries after a failed enable; it fails (no retry) on the previous code.

handleNavigate's `Page.frameNavigated` handler called
`acceptLifecycleEvent("commit", frameId)` without the frame's loaderId.
Once `Page.navigate` resolves, the loader guard always carries the new
loaderId, so `eventLoaderIsRelevant(undefined, guard)` rejected the
commit event outright.
The navigation still completed in the common case only because the
readyState probe short-circuited first. On cross-origin navigations the
probe returns null (the old execution context has been destroyed), so
the wait fell back to `frameNavigated` — which was then rejected — and
`wait_until="commit"` timed out for the full `timeout_ms` instead of
resolving on commit.
Pass `p.frame?.loaderId` through, matching the sibling `lifecycleEvent`
branches. Adds a regression test that makes the readyState probe fail
and asserts commit is reached from the `frameNavigated` event; it fails
(reached "timeout") on the previous code.

If `chrome.debugger.attach` succeeds but a subsequent CDP domain enable
rejects — most notably `Page.enable`, when the tab navigates to a
chrome:// URL or the Web Store in the gap between the two calls — the
driver left the tab in an unrecoverable state. `attachedTabs` never
recorded the tabId, so the next `ensureAttached` re-attached and failed
permanently with "Another debugger is already attached" until the
extension was reloaded.
Detach the debuggee directly in the failure path (the public `detach()`
is a no-op here because the id is not cached yet) so the next attempt
starts from a clean slate. Adds a regression test that fails on the
previous code, where the rollback never ran and `detach` was never
called.

Add a popup launcher + action-recording panel that builds a copyable
`bsk record start` prompt, add `--browser` targeting, and default `--url`
to https://example.com/ when omitted. Drop the popup browser-alias field.
The manifest now declares a minimum Chrome version and requests the
`idle` permission, and the runtime gains the WebSocket heartbeat and
wake-driven reconnect. Publishing that update requires a new version.

Harden the extension's connection so the daemon link survives normal
idle periods and OS sleep instead of silently dropping.
- Send a `system.heartbeat` event every 20s while the post-handshake
link is live. Since Chrome 116 WebSocket activity resets the MV3
service-worker idle timer, so this keeps the worker (and the socket)
alive during use rather than relying on the 30s keepalive alarm that
sits right on the eviction boundary. Declare `minimum_chrome_version:
"116"` accordingly.
- Reconnect on `runtime.onStartup` and `idle.onStateChanged` ("active"),
which revive the worker after a browser restart or machine wake and
let it reconnect immediately instead of waiting for the next alarm
tick. Add the `idle` permission and document it.

Capture user actions in the Agent Window and export a record-only
trace (pages[] + navigate/click/fill/select/press steps with target
descriptors). Adds the record overlay UI aligned with the control
overlay, and wires record start/stop/await through CLI, daemon,
protocol, and extension.
