0.1.3

Harden remote terminal; add clipboard & visualizers

Lock down and extend the LAN-served remote terminal: implement path allowlist and sensitive-file deny rules, symlink-aware reads, per-session rate limits, strict WebSocket Origin checks, CSRF/content-type checks for /api/auth, security response headers, and token expiry. Improve media delivery with a privileged fterm:// scheme, range-capable streaming for audio/images, image size caps, and static asset serving for air-gapped clients; add mobile-friendly client UI (Term/AI/Tools tabs, sticky modifier keys, quick-launchers) and numerous widget parity features. Add clipboard history support (main-process polling, pin/delete/clear APIs, preload bindings, and renderer events) and a new audio visualizer widget plus many visualizer modules. Misc: expose deployFtermFetch from ptyManager, add streamAIRequest entrypoint for remote streaming, refine various IPC responses/errors, and update README/CHANGELOG to document changes.
