- Rust Frontmatter struct now parses both 'type' (new) and 'Is A'/'is_a' (legacy),
with 'type' taking precedence via resolve_type()
- Added migrate_is_a_to_type() vault-wide migration (runs on startup, also exposed as Tauri command)
- Frontend: buildNoteContent and resolveNewType now emit 'type:' in YAML
- Inspector SKIP_KEYS hides 'is_a', 'Is A', 'type', 'title' from property list
(TypeRow already renders the type with its dedicated UI)
- frontmatterToEntryPatch handles both 'type' and legacy 'is_a' keys
- Mock data updated: all YAML content uses 'type:' instead of 'is_a:'/'Is A:'
- Tests updated to expect 'type:' in generated frontmatter
Product decision: internal VaultEntry field stays as `isA` (TS) / `is_a` (Rust)
to minimize blast radius. The user-facing change is the YAML key and inspector.
