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

When users press Ctrl+C to exit `shopify theme dev`, the keypress handler
called `process.exit()` synchronously — skipping the oclif post-run hook
where analytics normally fire, so no event reached Monorail.

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 real 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.

+Fix `theme dev` analytics being dropped on Ctrl+C. The command called `process.exit()` synchronously inside the keypress handler, which skipped the oclif post-run hook where analytics normally fire. The fix emits the event inline before exit.
