* fix(libsql): support flexible embedding dimensions (#494)
The libSQL schema hardcoded F32_BLOB(1536) for the embedding column,
preventing use of models with other dimensions (e.g. 768-dim
nomic-embed-text). This adds incremental migration support to the
libSQL backend and a V9 migration that rebuilds the memory_chunks
table with a plain BLOB column accepting any dimension.
- Add incremental migration infrastructure (INCREMENTAL_MIGRATIONS
array + run_incremental() runner tracked via _migrations table)
- V9 migration rebuilds memory_chunks with BLOB column, drops the
vector index (which requires fixed-dimension F32_BLOB)
- Update base schema for fresh installs (BLOB, no vector index)
- Vector search gracefully falls back to FTS-only when the index
is absent (matches PostgreSQL behavior after its V9 migration)
- Remove now-incorrect "dimension is not 1536" warnings
Existing embeddings are preserved during migration. Users only need
to re-embed if they change their embedding model/dimension.

* fix: wrap incremental migrations in transaction for atomicity
Address PR review feedback: if the process crashes after executing
migration SQL but before recording it in _migrations, the migration
would be applied but not marked complete. Wrapping both operations
in a transaction ensures they succeed or fail together.

* fix(workspace): thread document path through search results
Memory search results were showing chunk UUIDs instead of source file
paths. Thread document_path through RankedResult, SearchResult, and the
RRF fusion pipeline so handlers can display the actual file path.

* refactor: use into_iter to move values instead of cloning
Address review feedback: consume results with into_iter() to move
String fields directly instead of cloning them.

* refactor: split large files and consolidate test stubs for contributor velocity
- Extract 7 Database sub-traits (ConversationStore, JobStore, SandboxStore,
RoutineStore, ToolFailureStore, SettingsStore, WorkspaceStore) with Database
as a supertrait combining them all
- Split libsql_backend.rs (2769 lines) into src/db/libsql/ directory with
one file per sub-trait implementation
- Split config.rs (1753 lines) into src/config/ directory with 16 domain files
- Consolidate 3 duplicate test LLM stubs into shared StubLlm in src/testing.rs
- Split server.rs handlers into src/channels/web/handlers/ directory
- Extract main.rs init phases into AppBuilder (src/app.rs)
- Add developer setup script (scripts/dev-setup.sh)

* fix: address PR review comments from Copilot
- tunnel.rs: replace .ok().flatten() with ? to propagate env var errors
- secrets.rs: remove misleading "process-wide cache" comment
- database.rs: use uppercase "DATABASE_URL" in error key
- testing.rs: gate harness tests with #[cfg(feature = "libsql")]
