kshitijk4poor 37a1c75716 fix(browser): hardening — dead code, caching, scroll perf, security, thread safety ...

Salvaged from PR #7276 (hardening-only subset; excluded 6 new tools
and unrelated scope additions from the contributor's commit).

- Remove dead DEFAULT_SESSION_TIMEOUT and unregistered browser_close schema
- Fix _camofox_eval wrong call signatures (_ensure_tab, _post args)
- Cache _find_agent_browser, _get_command_timeout, _discover_homebrew_node_dirs
- Replace 5x subprocess scroll loop with single pixel-arg call
- URL-decode before secret exfiltration check (bypass prevention)
- Protect _recording_sessions with _cleanup_lock (thread safety)
- Return failure on empty stdout instead of silent success
- Structure-aware _truncate_snapshot (cut at line boundaries)

Follow-up improvements over contributor's original:
- Move _EMPTY_OK_COMMANDS to module-level frozenset (avoid per-call allocation)
- Fix list+tuple concat in _run_browser_command PATH construction
- Update test_browser_homebrew_paths.py for tuple returns and cache fixtures
