fix(theme): restore theme dev analytics on Ctrl+C exit

When users pressed Ctrl+C to exit `shopify theme dev`, the keypress handler
called `process.exit()` synchronously, bypassing the oclif post-run hook
where analytics normally fire. As a result, no event reached Monorail for
clean Ctrl+C exits.

Fix by emitting `reportAnalyticsEvent({exitMode: 'ok'})` inline inside
`dev()` before `process.exit(0)` and populating `store_fqdn_hash` metadata
at the same point, since the `finally { logAnalyticsData }` in
`theme-command.ts` is also skipped by the hard exit. A module-level
`hasReportedAnalyticsEvent` guard prevents double-emit if a later throw
bubbles to `errorHandler`.

Adds a unit test that mocks `reportAnalyticsEvent` and asserts it fires
exactly once with the expected payload, with correct call order vs
`process.exit(0)` verified via `invocationCallOrder`. The test also
covers the once-per-exit invariant and the double-emit guard inline.
