Add optimized repository methods for resolve_permalink() that skip
eager loading of observations and relations:
- permalink_exists(): Check existence without loading entity
- get_file_path_for_permalink(): Get only file_path column
- get_permalink_for_file_path(): Get only permalink column
- get_all_permalinks(): Get all permalinks as strings
- get_permalink_to_file_path_map(): Bulk lookup mapping
- get_file_path_to_permalink_map(): Reverse mapping
Updated entity_service.resolve_permalink() to use these lightweight
methods instead of loading full entities with all relationships.
Also added logfire instrumentation to markdown utils.

1. Hashtag detection now checks for standalone words starting with #
instead of just checking if # appears anywhere in content.
This prevents HTML color codes like #4285F4 from being
interpreted as hashtags.
2. Observation permalinks now truncate content to 200 chars
to stay under PostgreSQL's btree index limit of 2704 bytes.
Added tests for both fixes.
