Implements tag/category system backend following microformats2 p-category specification.
Database changes:
- Migration 008: Add tags and note_tags tables
- Normalized tag storage (case-insensitive lookup, display name preserved)
- Indexes for performance
New module:
- starpunk/tags.py: Tag management functions
- normalize_tag: Normalize tag strings
- get_or_create_tag: Get or create tag records
- add_tags_to_note: Associate tags with notes (replaces existing)
- get_note_tags: Retrieve note tags (alphabetically ordered)
- get_tag_by_name: Lookup tag by normalized name
- get_notes_by_tag: Get all notes with specific tag
- parse_tag_input: Parse comma-separated tag input
Model updates:
- Note.tags property (lazy-loaded, prefer pre-loading in routes)
- Note.to_dict() add include_tags parameter
CRUD updates:
- create_note() accepts tags parameter
- update_note() accepts tags parameter (None = no change, [] = remove all)
Micropub integration:
- Pass tags to create_note() (tags already extracted by extract_tags())
- Return tags in q=source response
