Implements the four §3 fixes from the check-wait design doc:
- §3.1 Transport keepalive: long-poll RPCs (orchestration.check --wait) emit
`{"_keepalive":true}` frames every 10s so neither server nor client tears
the socket down on idle. A `longPoll` admission counter capped at 16 fails
fast with `runtime_busy` when saturated; an AbortController wired through
the RPC dispatcher cancels the inner waiter the moment the socket closes.
- §3.2 delivered_at split: push-on-idle now stamps `delivered_at` instead of
flipping `read`, so the check caller remains the sole consumer of its
queue. Adds a synchronous idempotent schema migration that hard-fails on
error.
- §3.3 inbox/check parity: `orchestration inbox --terminal <handle>` and
`orchestration check --all` agree on the same rows (sequence DESC, no
mark-read). `check --unread=false` kept for one release as a compat shim.
- §3.4 CLI heartbeat: `orca orchestration check --wait` emits JSON heartbeat
lines to stderr every 15s so Claude Code's Bash tool sees continuous
output and doesn't auto-background the subprocess.
Tests: extends runtime-rpc, orca-runtime, envelope-schema, orchestration
method, and formatter suites; adds a subprocess test that spawns the built
CLI and verifies stderr line-flushing, heartbeat cadence, and stdout
cleanliness end-to-end.

[New] Annotate AI Diff
Comment directly on AI-generated diffs.
Annotate any line in an AI-generated diff with your feedback, then send it back to the agent to revise. Keep the review loop tight — no copying line numbers, no context switching.
[New] Hot Swap Codex Accounts
Multiple Codex accounts? Switch in one click.
If you run multiple Codex accounts to get the best token deal, Orca lets you hot-swap between them instantly — no re-login, no config files. Just pick an account and keep building.
[New] Per Worktree Browser & Design Mode
See your app. Click any element. Drop it into the chat.
Orca ships with a built-in browser right inside your worktree. Preview your app as you build, then switch to Design Mode — click any UI element and it lands directly in your AI chat as context. No screenshots, no copy-pasting selectors. Just point at what you want to change and tell the agent what to do.
[New] Introducing the Orca CLI
Agent orchestration from your terminal.
Let your AI agent control your IDE. Use AI to add projects to your IDE, spin up worktrees, and update the current worktree's comment with meaningful progress checkpoints directly from the terminal. Ships with the Orca IDE (install under Settings).
