Add Bugfix Workflow community extension to catalog and README (#2135)

* Add Bugfix Workflow community extension to catalog and README

Adds the spec-kit-bugfix extension (3 commands, 1 hook) that provides a
structured bugfix workflow — capture bugs, trace to spec artifacts, and
surgically patch specs without regenerating from scratch.

Addresses community request in issue #619 (25+ upvotes, maintainer-approved).
