feat(store): Postgres adapter foundation + BF_DB selector (phase 1)
Lays groundwork for sqlite|postgres backend selection without yet converting Repository. Adds: - db-adapter.ts: async DbAdapter interface (run/get/all/exec/transaction) - sqlite-adapter.ts: wraps node:sqlite sync API in Promise-returning shape, caches prepared statements - pg-adapter.ts: pg Pool + ? → $N placeholder rewrite + RETURNING-id capture + savepoint-nested transactions - service-store config: driver (sqlite|postgres), pgUrl - BF_DB env override, plumbed via envStr Selecting BF_DB=postgres throws at init() until the Repository is converted off DatabaseSync. This commit ships the foundation only. Next phases (separate commits): 2. Convert Repository methods sync → async via DbAdapter 3. Update every caller to await 4. Split MIGRATIONS into sqlite + portable / pg-specific sets 5. UUIDv7 IDs for new tables on PG path Adds deps: pg ^8.13.1, uuidv7 ^1.0.2, @types/pg ^8.20.0

|

* Backend-agnostic DB adapter. Repository talks to this; concrete adapters

* (sqlite, postgres) implement it.
|
||||
*
|
||||
* Design choices:
|
||||
* - All methods return Promises so the Postgres path can use real async I/O.
|
||||
* The SQLite adapter wraps node:sqlite's synchronous calls in
|
||||
* Promise.resolve to keep the same interface.
|

* - `?` is the canonical placeholder in SQL strings. The Postgres adapter
|
||||
* rewrites them to `$1, $2, ...` at execute time so repository code stays
|
||||
* dialect-neutral.
|
||||
* - INSERTs that need to return the new row id must use `... RETURNING id`
|
||||
* explicitly. Both SQLite (3.35+) and Postgres support it.
|
||||
*
|
||||
* Migrations and DDL fragments still differ between dialects (AUTOINCREMENT
|
||||
* vs SERIAL, STRICT vs nothing, strftime vs now()), so each backend ships
|
||||
* its own migration set rather than trying to abstract DDL.
