* feat(desktop): restart local daemon when bundled CLI version differs

Desktop bundles a multica CLI binary at build time via bundle-cli.mjs.
If a local daemon is already running from a previous session with an
older CLI, the newly bundled version never takes effect until the user
manually restarts. Fix that on the login/auto-start path.

- Expose the daemon's CLI version on GET /health as cli_version (sourced
  from cfg.CLIVersion, which is already set from the ldflag at daemon
  startup in cmd_daemon.go).
- In the desktop main process, query the resolved CLI binary's version
  once via `multica version --output json` and cache it for the process
  lifetime.
- On daemon:auto-start, if the daemon is already running, compare the
  two versions. Restart only when BOTH sides are known and the strings
  differ — a restart kills in-flight agent tasks, so any uncertainty
  (bundled CLI unknown, older daemon without cli_version field, read
  failure) fails safe and leaves the daemon alone.

* feat(daemon): defer version-mismatch restart until active tasks drain

Previous iteration restarted the daemon immediately on a confirmed CLI
version mismatch, which would kill any agent tasks mid-execution. Gate
the restart on an active-task counter so in-flight work always finishes.

- Daemon: add `activeTasks atomic.Int64` on the Daemon struct,
  increment/decrement it around handleTask, and expose it as
  `active_task_count` on GET /health.
- Desktop: when a version mismatch is confirmed but active_task_count >
  0, set a pendingVersionRestart flag instead of restarting. The 5s
  pollOnce loop retries ensureRunningDaemonVersionMatches on each tick
  and fires the restart the moment the count drops to 0.
- Eventual consistency: if the user keeps the daemon permanently busy,
  the version stays out of date — that's a strictly better failure mode
  than silently killing hour-long agent runs.

* test(daemon): cover version-check decision + /health counter exposure

Addresses the test-coverage gap from the second review.

- Go: extract the /health handler into a named method `(d *Daemon)
  healthHandler(startedAt time.Time)` so it can be exercised via
  httptest without spinning up a listener. Add health_test.go covering
  cli_version + active_task_count field exposure and the increment /
  decrement protocol used by pollLoop.
- Desktop: extract the pure version-check decision logic into
  version-decision.ts (no electron, no I/O, no module state). The
  ensureRunningDaemonVersionMatches wrapper now delegates the "what
  should we do" decision to decideVersionAction and owns only the side
  effects (logging, flag mutation, restartDaemon call).
- Desktop: bolt vitest onto apps/desktop (vitest.config.ts + catalog
  devDep + test script) so main-process unit tests have a home. Add
  version-decision.test.ts covering all four action branches and the
  busy→idle drain transition.

* fix(daemon): bust CLI version cache on retry-install, lock wire-level JSON keys

Two polish items from review.

- daemon:retry-install now also clears cachedCliBinaryVersion. Previously
  a retry that landed a newly-downloaded CLI at a different version
  would false-negative on the next version check because the cached
  version string was sticky for the process lifetime.
- TestHealthHandlerReportsCLIVersionAndActiveTaskCount now decodes into
  a raw map[string]any and asserts the exact snake_case keys
  (cli_version, active_task_count, status). The desktop TS client keys
  on these literal strings, so a silent struct-tag rename must fail the
  test. Typed struct round-trip kept as a separate value check.
