Add SpecTest extension to community catalog (#2159)

* Add SpecTest extension to community catalog

Adds spec-kit-spectest: auto-generate test scaffolds from spec criteria.

4 commands:
- /speckit.test.generate — generate framework-native test scaffolds
- /speckit.test.coverage — map spec requirements to test coverage
- /speckit.test.gaps — find untested requirements with suggestions
- /speckit.test.plan — generate structured test plan documents

1 hook: after_implement (gap detection)

Bridges the spec-to-test gap in the SDD workflow.

* Update extensions/catalog.community.json

* Fix spectest created_at/updated_at to use current timestamp per Copilot review

Set both to 2026-04-10T16:00:00Z instead of midnight.
