PostgreSQL rejects null bytes (0x00) in text columns, causing
CharacterNotInRepertoireError when syncing files like Claude agent
definitions that contain embedded nulls. SQLite silently accepts them,
so this only surfaces in cloud environments.

frontmatter.Post.__init__ takes `content` and `handler` as positional
parameters. When user YAML frontmatter contains these as field names,
unpacking metadata via **kwargs causes "got multiple values for argument
'content'".
Replace frontmatter.loads() with frontmatter.parse() + Post() + update()
in entity_parser, and replace the **metadata unpacking in
entity_service.update_entity() with the same safe pattern.

YAML block sequence syntax can cause PyYAML to parse scalar fields like
`title` and `type` as lists instead of strings. Downstream code calls
.strip()/.casefold() on these values, crashing with
"'list' object has no attribute 'strip'".
Add _coerce_to_string() helper that joins list items with ", " and apply
it in entity_parser.parse_markdown_content() and
entity_service.fast_edit_entity() where these fields are extracted.

Refactor importers to use FileService for all file operations instead of
direct filesystem calls. This enables cloud environments to override file
operations via dependency injection (e.g., S3FileService).
Changes:
- Add `to_markdown_string()` method to MarkdownProcessor for content
serialization without file I/O
- Update Importer base class to accept FileService and use it for:
- `write_entity()` - now uses FileService.write_file()
- `ensure_folder_exists()` - now async, uses FileService.ensure_directory()
- Fix direct `mkdir()` calls in:
- claude_projects_importer.py
- memory_json_importer.py
- Update deps.py to inject FileService into all importers (v1 and v2)
- Update CLI commands to create and pass FileService to importers
- Update tests to work with new FileService dependency
This follows the pattern used by /knowledge API and SyncService, enabling
cloud to override file operations by providing S3FileService via DI.

Fixes#452 - Imported conversations not fully indexed
Files with UTF-8 BOM (Byte Order Mark) at the start would fail frontmatter
detection, causing:
- Title to fall back to filename instead of frontmatter value
- Permalink to be null in the database
Added strip_bom() helper function and updated all frontmatter-related
functions to strip BOM before processing:
- has_frontmatter()
- parse_frontmatter()
- remove_frontmatter()
- EntityParser.parse_markdown_content()
Added comprehensive tests for BOM handling with various scenarios.

Denormalizes project_id onto Relation and Observation tables to enable
efficient project-scoped queries without joins. Migration backfills
from associated entity and adds pg_trgm extension with GIN indexes
for fuzzy link resolution on PostgreSQL.

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.

feat: Add multiple projects support
feat: enhanced read_note for when initial result is not found
fix: merge frontmatter when updating note
fix: handle directory removed on sync watch
Replace frontmatter properties with top-level attributes for `created` and `modified` to simplify handling and ensure consistent attribute usage. Added a utility function for schema-to-markdown conversion and updated related tests and code to reflect these changes.
