Bundle FiraCode Nerd Font directly in static assets so terminal rendering no longer depends on host-installed Nerd Fonts.
Changes included:
- Added vendored font asset at webterm/static/fonts/FiraCodeNerdFont-Regular.ttf.
- Added bundled font license at webterm/static/fonts/FiraCode-LICENSE.txt.
- Wired local @font-face declarations in webterm/static/monospace.css for both "FiraCode Nerd Font" and "FiraMono Nerd Font" family names used by the existing font stack.
- Documented the capability in README Features as a first-class feature with full glyph/icon support and no external font fetch requirement.
Impact:
- Font glyph/icon rendering is now more consistent across environments.
- Font assets continue to be embedded in the Go binary by default through the existing static embed path.

Address intermittent stalls seen after many hours by improving liveness detection and failure handling for both streaming channels.
WebSocket changes:
- Added periodic server ping frames and a read deadline refreshed by pong replies.
- On sender write/ping failure, explicitly close the underlying connection so clients promptly observe disconnect and reconnect instead of remaining half-open.
SSE changes:
- Excluded /events from gzip middleware and added X-Accel-Buffering: no to reduce proxy buffering risk.
- Stop the SSE loop on write errors for activity/keepalive frames so dead subscribers are cleaned up immediately.
Tests:
- Added regression coverage for gzip bypass on /events.
- Added regression coverage ensuring SSE handler exits and unsubscribes on write failure.
- Verified with make format && make check.
