chore: CLI live-reconnect workstream completion (fix in kilocode#12393)

[iscekic]

Workstream completion vehicle — CLI live-reconnect

This is the cloud-repo completion tracker for the CLI live-reconnect fix. The defect and its fix are entirely in the Kilo CLI connection layer, so this PR carries no cloud code changes.

• The actual fix lives in the kilocode repository: fix(cli): recover remote session connection that silently dies and never reconnects kilocode#12393 — "fix(cli): recover remote session connection that silently dies and never reconnects".
• This branch was originally cut from the (then-unmerged) .kilo mobile-workflow docs branch; those docs have since merged into main via docs(mobile): reviewer loop, Opus 4.8 orchestrator, and pre-plan bug repro gate #4619, so the net file diff of this PR against main is empty.

Summary of the delivered fix (see kilocode#12393 for the code)

A remote CLI session could silently lose its session-ingest connection and never reconnect until the CLI was restarted, leaving the mobile app showing a live CLI session as frozen/read-only. Root causes were all in the CLI client: unbounded token acquisition, an unbounded CONNECTING attempt, and a wedged heartbeat gather that permanently stopped heartbeats across reconnects. The fix bounds token acquisition, adds a single fenced retry owner with a connection-attempt deadline, bounds the heartbeat gather with a degraded last-known-good fallback, and fences attach announcements on fresh-gather session-id containment.

Verification (performed against this worktree's local stack)

• Deterministic unit coverage: 16 acceptance tests fail on the unmodified baseline and pass on the fix; remote-ws.test.ts 39 pass, attached-state.test.ts green, typecheck clean.
• On-device E2E: healthy session renders live with a working composer; after a connection drop the CLI auto-reconnects (same process, no restart) and the session returns live on mobile.

Executive Summary

This PR is a workstream-completion tracker whose net diff against current main is empty (the referenced .kilo docs changes already merged via #4619), and the actual fix lives in Kilo-Org/kilocode#12393, so there is no cloud-repo code to review.
