- feat(acp): persist in-flight session state across tab close/reopen, browser refresh, and reconnects. The streaming reply, active tool calls, pending permission prompts, plan updates, modes and usage all rehydrate from a backend snapshot, with seq-based deduplication against the live event stream.
- feat(acp): harden the connection lifecycle with an idle sweep, spawn deduplication mutex, serialized prompt sends, and a close-error state machine; sends are cancelled on failure and stuck spawns no longer wedge the session.
- feat(acp): keep open conversation tabs alive via a frontend keepalive so connections aren't reaped while the user is still looking at them.
- feat(acp): create the conversation row on the first prompt and emit a conversation_linked event, eliminating duplicate rows when the same prompt is sent twice in quick succession.
- fix(web-server): release the listening port reliably on shutdown and surface stale-port state instead of silently failing to restart.
- fix(web): fall back to a clipboard shim on non-secure contexts so copy actions work over plain HTTP.
- fix(workspace-state): apply the cold-scan snapshot after stream restarts and catch up missed deltas when re-acquiring within the shutdown grace window.
- fix(mobile-web): improve mobile web UI control accessibility. Thanks to @pia for contributing this fix in #122.
