The Image text-fallback render does not respect the rendered width,
so a long file path can blow past the terminal width and crash the
host TUI. Wrap the component to truncate each rendered line with
truncateToWidth so it fits the available width.

- Add lightweight async mutex (src/util/mutex.ts) for FIFO serialization
- Add serialized?: boolean to BrowserToolDefinition
- Wire mutex acquisition into registerBrowserTool execute wrapper
- Expose mutationMutex() on BrowserClient
- Mark all mutation tools (click, type, scroll, navigate, switch_tab, etc.) as serialized
- Leave observation tools (screenshot, page_info, execute_js, http_get, etc.) unguarded
- Update prompt and skill docs to reflect parallel-safe behavior
- Fix scroll tool: add Page.bringToFront, explicit button:none/buttons:0/pointerType:mouse
- Update .gitignore to ignore scripts/ and data/ folders

parallelization guidance to SKILL.md
- browser_screenshot now has renderResult that creates an Image component
for inline display in Kitty/iTerm2/Ghostty/WezTerm terminals
- Falls back to dim text placeholder on terminals without image support
- Updated system prompt table description to mention TUI inline rendering
- Added Parallelization section to SKILL.md teaching the agent to batch
independent operations (browser_open_urls, browser_http_get, etc.)

matching, download auto-mkdir, session recovery, docs updates
Bug fixes:
- list_tabs: show full 32-char targetIds (was truncated to 8 chars)
- switch_tab: prefix matching fallback for hex prefixes >= 8 chars
- download: auto-create directory with mkdir -p
- ensureAlive: Runtime.evaluate probe to recover from crashed page targets
Docs:
- dispatch_key: clarify DOM-only event behavior
- navigate: warn about Google anti-bot limitation
- network_log: update deprecated promptSnippet
- SKILL.md: document actual daemon API (evaluateJs, pageInfo, session.call)
- SKILL.md: add troubleshooting for sharp/maxDim and Google navigation
- sharp: add to optionalDependencies for screenshot maxDim auto-resize

document IIFE-wrap heuristic, log shutdown failures, fix CHANGELOG file-size claim
Five tweaks from the whole-implementation review:
- session.ts: log unexpected event-consumer rejections instead of silent swallow
- client.ts: comment the return-substring IIFE-wrap false-positive case
- transport.ts: comment that ws.onclose post-open settle is no-op-by-design
- index.ts: log client.stop() failures during shutdown
- CHANGELOG.md: correct largest-file claim (transport.ts and client.ts are ~220 each, not "client.ts at ~180")

Implements Task 9: adds src/domains/click.ts with the new architecture,
updates registry.ts to register clickTool, removes the legacy browser_click
block from tools.ts, and wires BrowserClient alongside BrowserDaemon in
index.ts so both systems coexist during migration.
Also fixes AnyBrowserToolDefinition variance: uses never-arg renderCall in
the erased type and a boundary cast in registerBrowserTool so concrete tool
definitions (with specific Static<S> args) are assignable to the registry
array without widening.

Adds the missing tools called out in docs/browser-harness-comparison.md:
upload_file, dispatch_key, download (configure dir), viewport_resize,
drag_and_drop, print_to_pdf, get_network_log, plus the iframe-target
helper. Updates promptGuidelines and the system prompt's tools table.
Tracked in todo.md.

screenshots, page info caching
5 performance optimizations (14-36% faster end-to-end, output quality unchanged):
- fast ensureAlive(): WS state check instead of CDP roundtrip (96% faster per-call)
- event-based waitForLoad(): CDP load events instead of 300ms polling (99.5% faster for loaded tabs)
- JPEG screenshot support: 29-49% smaller files, faster CDP transfer
- page info caching: 1s TTL eliminates redundant evaluateJS calls
- parallel domain enables: Promise.all instead of sequential await in switchTab()
Benchmark: 3622ms vs 4243ms baseline on 3-tab navigation + screenshot task.

Remove register_tool/remove_tool/list_dynamic_tools and the entire
dynamic-tools.ts module. Replace with a single browser_run_script tool
that executes temporary scripts from disk with daemon access.
Scripts are now written to disk before execution, making them auditable
and re-runnable. Same bindings (daemon, require, params, etc.) as before
via the same AsyncFunction mechanism.

Previously a single consent-pending socket could spawn up to 5 stacked
'Allow remote debugging?' dialogs. Three causes:
- onopen reset _reconnectAttempts, but Chrome accepts the WS upgrade
before the user clicks Allow, so a held socket looked healthy.
- ensureAlive's health probe used the full 15s CDP timeout; while the
user was reading the dialog the probe would time out, trigger a
stop()+start(), and a fresh popup would stack on top.
- onclose auto-reconnected unconditionally even when consent had never
been granted on that connection.
Now a connection is only considered healthy once the first CDP
roundtrip completes (attachFirstPage). ensureAlive does a 2s short
probe before tearing down the socket. onclose bails out of auto-
reconnect when consent was never observed, so a denied dialog
surfaces a clean error instead of looping.

Drops the Unix socket subprocess in favor of talking CDP directly over
WebSocket from the extension. Removes the protocol's send/health helpers,
simplifies setup to just verifying Chrome's remote debugging port, and
tightens types in dynamic-tools. Bumps Node engine to >=22 and adds the
ws dependency.

Browser control extension for pi — 20 browser_* tools for navigating,
clicking, typing, screenshotting, and extracting data from real Chrome
via CDP. Includes self-extending harness (register_tool/remove_tool),
guided /browser-setup, session persistence, and custom TUI renderers.
