Jan De Landtsheer 5715f585fd feat(storage): phase 1 -- extract MemoryStore and Embedder traits (ADR 0001)
Introduce two trait boundaries that the rest of the stack now sits above,
landing Phase 1 of ADR 0001 (pluggable storage and network access).
Rebased onto v2.1.22 Sanhedrin from the original April work.

MemoryStore / LocalMemoryStore (crates/vestige-core/src/storage/memory_store.rs):
  One trait, ~25 methods, covering CRUD, hybrid / FTS / vector search,
  FSRS scheduling, graph edges, and the forthcoming domain surface.
  trait_variant::make generates a Send-bound MemoryStore alias over the
  base LocalMemoryStore so Arc<dyn MemoryStore> works under tokio/axum.
  Storage errors map through a dedicated MemoryStoreError.

Embedder / LocalEmbedder (crates/vestige-core/src/embedder/):
  Pluggable text-to-vector encoder. FastembedEmbedder wraps the existing
  EmbeddingService; storage never calls fastembed directly anymore.
  Embedder::signature() produces the ModelSignature consumed by the
  store's embedding_model registry.

SqliteMemoryStore (crates/vestige-core/src/storage/sqlite.rs):
  Storage renamed to SqliteMemoryStore; the old name lives on as a
  pub type alias so Arc<Storage> consumers in vestige-mcp stay intact.
  All existing inherent methods are untouched; the trait impl is
  purely additive and dispatches into them. The db_path field added
  by v2.1.1 portable-sync is preserved.

Migration V14 (crates/vestige-core/src/storage/migrations.rs):
  Renumbered from V12 (the original April number) to V14 to slot in
  cleanly after upstream's V12 (v2.1.1 sync_tombstones) and V13
  (v2.1.2 purge tombstones).
  - embedding_model registry table (CHECK id = 1, code enforces the
    single-row invariant).
  - knowledge_nodes.domains / domain_scores TEXT columns (JSON arrays
    default '[]' / '{}'), domains catalogue table, supporting indexes.
  Phase 4 populates these columns; Phase 1 just exposes the schema.

Consolidation and other cognitive pathways now accept a
&dyn LocalMemoryStore (sync) or Arc<dyn MemoryStore> (async) rather
than a concrete Storage.

Tests:
  - trait-method unit tests colocated in sqlite.rs and migrations.rs
  - embedder/fastembed.rs tests for name/dimension/hash stability
  - new integration crate tests/phase_1 (added to workspace members):
    trait_round_trip (8), embedding_model_registry (7),
    domain_column_migration (5), cognitive_module_isolation (4),
    send_bound_variant (2), embedder_trait (2).

Acceptance gate post-rebase:
  - cargo build --workspace --all-targets: ok
  - cargo clippy --workspace --all-targets -- -D warnings: clean
  - cargo test -p vestige-core --lib: 428 pass
  - cargo test -p vestige-phase-1-tests: 28 pass
  - cargo test -p vestige-mcp --lib: 380 pass (Storage alias preserves
    every existing call site)

Co-existence with v2.1.1 portable-sync: this trait extraction is
additive. Portable-sync's tombstone migrations (V12, V13) remain
on the concrete SqliteMemoryStore; Phase 2 (Postgres) will decide
which of those surfaces graduate into the trait.
