parseHeartbeat now reads an optional model= line from the heartbeat
file (written by native runtime heartbeats) into HeartbeatInfo.model,
and fleet ps surfaces it as a MODEL column (table) and in --json
(via rows[].heartbeat.model). Legacy/sidecar heartbeats omit the line
and report model=null, so the column shows '-'.
Closes the model self-report gap end-to-end with the native Pi
heartbeat writer (F3-m2): the runtime self-reports its active model
and the fleet operator can see it in ps.

WIP — not for merge yet. Implements the core of the custom Pi harness (R14/R15):
- runtime/pi/mosaic-extension.ts: native heartbeat — writes the same .hb contract
(ts/pid/status[/model]) on a MOSAIC_HEARTBEAT_INTERVAL timer; turn_start/turn_end
flip status busy/ok; model self-report via ctx.model; touches a .hb.native
precedence marker. Also FIXES a latent bug: session_end -> session_shutdown (the
old handler never fired) + corrects the import scope to @earendil-works/pi-coding-agent.
- start-agent-session.sh: sidecar DEFERS when the .hb.native marker is fresh
(< 2x interval), else writes the fallback — native precedence, sidecar fallback,
same contract so fleet ps is agnostic (per Lead's design). Generated script
validated (bash -n) + deferral/fallback behavior tested.
REMAINING before PR: surface model in `fleet ps` (parseHeartbeat + row); vitest for
the native-HB writer; "proper tool usage" (registerTool) piece; rebase onto #599's
%q sidecar (overlap on the printf line).

Fresh `mosaic gateway install` (npm) left the gateway DB schema empty —
sign-in 500'd with `relation "users" does not exist`, and every entry
point (auth, bootstrap setup) failed because they all query the users
table first. Five stacked bugs on the local (PGlite) tier:
1. `packages/db/package.json` `files: ["dist"]` excluded the `drizzle/`
SQL migrations from the published tarball.
2. `runMigrations()` only supports postgres-js — unusable for embedded
PGlite.
3. `apps/gateway/src/database/database.module.ts` never invoked
migrations at startup.
4. `createPgliteDb` didn't load pgvector, so migration 0001's
`CREATE EXTENSION vector` failed.
5. Drizzle's PG migrator wraps every migration in one outer
transaction, which trips Postgres' `check_safe_enum_use` on
migration 0009 (`ALTER TYPE ADD VALUE 'pending'` → `SET DEFAULT
'pending'` in the same tx).
Changes:
- Ship `drizzle/` in the published tarball.
- `createPgliteDb` loads `@electric-sql/pglite/vector`.
- New `runPgliteMigrations(handle)` walks the Drizzle journal and
runs each statement-breakpoint chunk through PGlite's `client.exec()`
(autocommit per statement). Records into `drizzle.__drizzle_migrations`
for interop with the postgres-js path. Per-statement try/catch
surfaces which statement of which migration failed.
- `DatabaseModule` runs migrations in `OnModuleInit` before
`app.listen()`. Local tier: explicit `runPgliteMigrations` then
`storageAdapter.migrate()`. Postgres tier: just `storageAdapter.migrate()`,
which already calls `runMigrations(url)` internally — no double-call.
- Removed `packages/storage/src/test-utils/pglite-with-vector.ts`. The
"intentionally not exported" rationale is moot now that migration
0001 forces pgvector load anyway. The integration test uses
`createPgliteDb` + `runPgliteMigrations` from `@mosaicstack/db`.
Tests: BetterAuth tables exist after migrate; idempotent (re-runs 0009);
partial-failure surfaces statement-level context and leaves no ledger row.
QA on a fresh PGlite install:
- `Applying PGlite schema migrations...` then `Initializing storage
adapter (pglite)...` in startup log.
- `GET /api/bootstrap/status` → `{"needsSetup":true}` HTTP 200 (was 500).
- `POST /api/bootstrap/setup` reaches Zod validator (was 500).
Scope: this PR fixes the local (PGlite) tier. Postgres-tier first
install still has the outer-transaction problem and a journal ordering
bug (0009's `when` < 0008's). Documented inline as TODO and in the
scratchpad — needs a separate change with real-Postgres validation.
