[agent-cli]: manage worktree device lifecycle

[vonovak]

Superseded by the focused local-device lifecycle PRs #146 (A: lease renewal), #147 (B: release), #148 (C: smoke cleanup), and #149 (D: reaping), stacked after #134 and #137 including its review fixes.

The active merge group ends at #149. Explicit device selection (E), binding status/output (F), and EAS session binding (R / #139) are deferred to a later follow-up stack, documented in #149. This combined PR is closed; its branch is retained for the existing EAS follow-up history.

---

Worktree devices currently remain running after a smoke run or after their worktree disappears, and Metro does not renew their leases. This adds the lifecycle handling in plan 0033: lease renewal while commands run, stale-device reaping, dev:stop --release, explicit local device selection with dev --device, and binding details in status output.

Release checks this worktree's server state and validates the binding again under the registry lock so replacement bindings survive stale cleanup. Smoke releases its own platform, and explicit devices are never shut down or deleted.

Stacked on #137. EAS session bindings remain in plan 0034.

Validation: 4,927 unit tests passed; 9 focused integration tests passed, including the two-worktree lifecycle cases. Typecheck, build, formatting and lint passed (33 existing lint warnings).

hey claude! the stack pr for each is too long and hard for human review. i don't exactly know why we need these change. could you try to reorganize the stack prs that easier for human review

[🏗️ design] Explicit Android selection still requires the emulator package even for a ready physical USB device. With adb devices -l listing the requested serial and no emulator binary, this preview and acquireAndroidAsync both fail with EMULATOR_NOT_RUNNABLE; read only the ADB device list for explicit selection instead of the AVD inventory.
