Option C: Rewrite gyandoot-browser for camoufox-browser@0.1.0 daemon IPC

Complete rewrite removing old HTTP REST client. The latest camoufox-browser
npm package (v0.1.0) uses Unix socket JSON-line IPC, not HTTP REST on :9377.

Changes:
- gyandoot-browser/client.rs: Full daemon IPC via Unix socket (~/.camoufox-browser/*.sock)
  - JSON-line protocol matching ensureDaemonRunning + daemon.js
  - Auto-launches browser on first command (daemon manages lifecycle)
  - Supports navigate, click, type, scroll, snapshot, search macros, tab management
  - Proper HeathResponse, NavigationResult, PageSnapshot types
- gyandoot-browser/lib.rs: Exports new client API (no SearchMacro enum, no SessionManager)
- gyandoot-browser/Cargo.toml: reqwest -> tokio Unix socket deps
- Removed: macros.rs, session.rs, snapshot.rs (all merged into client.rs)
- browser_manager.rs: Triggers daemon via npx, waits for Unix socket
- browser_tools.rs: Simplified API (no tab_id, no create_tab/close_tab)

Fix: camoufox-browser process exited with status 1 error on fresh install
