Garry Tan dc0bae82d3 fix: sidebar agent uses real tab URL instead of stale Playwright URL (v0.12.6.0) (#544) 
* fix: sidebar agent uses extension's activeTabUrl instead of stale Playwright URL

When the user navigates manually in headed Chrome, Playwright's page.url()
stays on the old page. The sidebar agent was using this stale URL in its
system prompt, causing it to navigate to the wrong page (e.g., Hacker News
instead of the user's current page).

The Chrome extension now captures the active tab URL via chrome.tabs.query()
and sends it as activeTabUrl in the /sidebar-command POST body. The server
prefers this over Playwright's URL. The URL is sanitized (http/https only,
control chars stripped, 2048 char limit) to prevent prompt injection.

* feat: connect-chrome pre-flight cleanup + improved onboarding docs

Adds Step 0 pre-flight cleanup that kills stale browse servers and cleans
Chromium profile locks before connecting. Improves the onboarding flow with
clearer instructions for finding the extension, opening the Side Panel, and
troubleshooting connection issues. Fixes Mode check from cdp to headed.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: sidebar agent test suite (layers 1-2)

Layer 1 (unit): 18 tests for URL sanitization in sidebar-utils.ts — http/https
pass, chrome:// rejected, javascript: rejected, control chars stripped, truncation.

Layer 2 (integration): 13 tests for server HTTP endpoints — auth, sidebar-command
queue writes, activeTabUrl override/fallback, event relay to chat buffer, message
queuing, queue overflow (429), chat clear, agent kill.

Source changes for testability:
- Extract sanitizeExtensionUrl() to browse/src/sidebar-utils.ts
- Add BROWSE_HEADLESS_SKIP env var to skip browser launch in HTTP-only tests
- Add SIDEBAR_QUEUE_PATH env var to both server.ts and sidebar-agent.ts
- Add SIDEBAR_AGENT_TIMEOUT env var to sidebar-agent.ts
- Sync package.json version to match VERSION (0.12.2.0)

* test: sidebar agent round-trip tests with mock claude (layer 3)

Starts server + sidebar-agent together with a mock claude binary (shell script
outputting canned stream-json). Verifies the full queue-based message flow:

- Full round-trip: POST /sidebar-command → queue → agent → mock claude → events → chat
- Claude crash recovery: mock exits 1, agent_error appears, status returns to idle
- Sequential queue drain: two rapid messages both process in order

* test: sidebar agent E2E tests with real Claude (layer 4)

Two E2E tests that exercise the full sidebar agent flow with real Claude:

- sidebar-navigate: POST /sidebar-command asking Claude to describe a fixture
  page, verify it responds with page content through the chat buffer
- sidebar-url-accuracy: POST with activeTabUrl differing from Playwright URL,
  verify the queue prompt uses the extension URL (the core bug fix)

Both registered as periodic tier (~$0.80 total, non-deterministic).

* fix: sidebar E2E tests — sequential execution + eval collector fix

Both tests now pass:
- sidebar-url-accuracy: deterministic queue file check (no Claude needed)
- sidebar-navigate: real Claude responds through sidebar agent queue

Fixed: testIfSelected (sequential, not concurrent) to avoid queue file
conflicts. Added cost_usd field for eval collector compatibility.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: kill stale sidebar-agent processes before starting new one

Each /connect-chrome starts a new sidebar-agent subprocess with unref()
but never kills the previous one. Old agents accumulate as zombies with
stale auth tokens. When they pick up queue entries, their event relay
fails (401), so the server never receives agent_done and marks the agent
as "hung". The user sees the sidebar freeze.

Fix: pkill any existing sidebar-agent.ts processes before spawning.
