feat(browse): $B cdp escape hatch — deny-default allowlist + two-tier mutex
Codex T2: flip CDP posture to deny-default. Allowed methods enumerated in
cdp-allowlist.ts with (scope: tab|browser, output: trusted|untrusted,
justification) per entry.

Initial allowlist (~25 methods) covers:
- Accessibility tree extraction (read-only)
- DOM/CSS inspection (read-only)
- Performance metrics
- Tracing
- Emulation viewport/UA override
- Page screenshot/PDF capture (output is binary, no marker injection vector)
- Network.enable/disable (no bodies/cookies — those are exfil surfaces)
- Runtime.getProperties (NO evaluate/callFunctionOn — those would be RCE)

Page.navigate is INTENTIONALLY NOT allowed; agents use $B goto which
goes through the URL blocklist.

Codex T7: two-tier mutex. tab-scoped methods take per-tab lock; browser-
scoped take global lock that blocks all tab locks. 5s acquire timeout
yields CDPMutexAcquireTimeout (no silent hangs). All lock acquires use
try/finally so errors don't leak the lock.

Path A from spike: uses Playwright's newCDPSession() per page. No second
WebSocket, no need for --remote-debugging-port. CDPSession is cached
per page in a WeakMap and cleared on page close.
