refactor: replace hardcoded Kind constants with rust-nostr variants

- Replace KIND_REPOSITORY_ANNOUNCEMENT with Kind::GitRepoAnnouncement
- Replace KIND_REPOSITORY_STATE with Kind::RepoState
- Replace KIND_PR with Kind::GitPullRequest
- Replace KIND_PR_UPDATE with Kind::GitPullRequestUpdate
- Replace KIND_USER_GRASP_LIST with Kind::GitUserGraspList
- Replace KIND_PATCH with Kind::GitPatch
- Replace KIND_ISSUE with Kind::GitIssue
- Replace KIND_COMMENT with Kind::Comment
- Replace all Kind::Custom(30617|30618|1617|1618|1619|1621|1111|10317) patterns
- Remove all hardcoded KIND_* constants from events.rs
- Update all match statements to use Kind enum directly
- Update all filter builders to use Kind variants
- Update all test helpers and assertions

Benefits:
- Type safety: compiler prevents wrong kind numbers
- Readability: Kind::GitRepoAnnouncement is self-documenting
- Maintainability: single source of truth (rust-nostr)
- IDE support: full autocompletion and refactoring
- Standards: aligns with rust-nostr best practices

Files modified: 21
Constants removed: 9
Patterns replaced: 100+
Tests passing: 222/222
