Update all backend code to use social.coves.community.comment
namespace instead of social.coves.feed.comment.

Changes:
- comment_consumer.go: Update collection constant and URI construction
- vote_consumer.go: Update comment collection matching for votes
- comment.go: Update lexicon reference in documentation
- comment_service.go: Update record type in buildCommentRecord
- view_models.go: Update lexicon references in comments
- lexicon.go: Update ValidateComment to use new namespace
- record_utils.go: Update example documentation

All URI construction now uses social.coves.community.comment
for new comment records and collection filtering in Jetstream
consumers.

Add migration 018 to update all comment URIs from
social.coves.feed.comment to social.coves.community.comment.

Migration updates:
- comments.uri (main comment URIs)
- comments.root_uri (when root is a comment)
- comments.parent_uri (when parent is a comment)

Includes rollback support via -- +goose Down section for safe
reversibility. Since we're pre-production, only the comments table
is updated (votes table not affected).

Migrate comment record lexicon from social.coves.feed.comment to
social.coves.community.comment to align with community-focused
architecture.

Changes:
- Move lexicon from feed/comment.json to community/comment.json
- Update lexicon ID: social.coves.community.comment
- Update test data lexicons (3 files) to use new namespace

This is part of the broader namespace migration to organize all
community-related records under the community namespace.

Add two new scripts for generating realistic test data:

- generate_deep_thread.go: Creates deeply nested comment threads (100 levels)
for testing threading logic, depth limits, and performance

- generate_nba_comments.go: Generates NBA-themed comments with realistic
basketball discussion content for UX testing and demos

Both scripts:
- Insert directly into PostgreSQL (bypassing Jetstream for speed)
- Create realistic comment trees with varied content
- Useful for stress testing, performance validation, and demos

Remove deprecated 'version' field from docker-compose.dev.yml.
Docker Compose v2 ignores this field and it's no longer needed.

Streamable and other providers return protocol-relative URLs (//cdn.example.com)
in their oEmbed thumbnail_url field. These fail when passed to the blob service
because http.NewRequest requires a full URL with scheme.

Fix:
- Add normalizeURL() helper to convert // → https://
- Apply to both oEmbed and OpenGraph thumbnail URLs
- Add comprehensive tests (6 test cases)

Example transformation:
//cdn-cf-east.streamable.com/image/abc.jpg
→ https://cdn-cf-east.streamable.com/image/abc.jpg

This ensures Streamable video thumbnails are properly downloaded and uploaded
as blobs, fixing missing thumbnails in video embeds.

Affects: All users posting Streamable/YouTube/Reddit links (not Kagi-specific)
Tested: Unit tests pass, build successful
