Rene Nochebuena 64ebf76f31 docs(db-postgres): fix fictional launcher.Register/health.Register in doc examples (#2) 
The package-doc examples showed a fictional launcher.Register / health.Register
API (and launcher.Append as a package func). Corrected to the real wiring:
lc.Append + web/health.NewHandler(...).ServeHTTP.

Documentation-only. No code, API, or dependency changes; version stays v1.1.0
(the v1.1.0 tag is moved to include this fix). Verified by compiling the
corrected pattern against the real API.

Rene Nochebuena fe3e0227d5 chore(db-postgres): bump einherjar deps to v1.1.0 (framework version alignment) (#1) 
Patch of the coordinated framework release: einherjar modules move to v1.1.0
in lockstep, so db-postgres is bumped alongside the rest.

- go.mod: contracts, core -> v1.1.0 (via go get + go mod tidy)

No code or API changes. ModuleVersion() reports v1.1.0 automatically from
build info once tagged. Badge bumped to v1.1.0.

Rene Nochebuena 4b58f8e3d9 feat(db-postgres): initial implementation — pgx pool with lifecycle and UnitOfWork (v1.0.0) 
Introduces code.nochebuena.dev/einherjar/db-postgres — the PostgreSQL database
starter for the Einherjar framework. Absorbs the postgres package from micro-lib,
replacing fmt.Errorf wrapping with core/xerrors and migrating from pgx v4 to pgx v5.

Interfaces (CT-6: one TypeSpec per file):
- Executor — Exec, Query, QueryRow (pgx-native types)
- Tx — Executor + Commit(ctx), Rollback(ctx)
- Provider — GetExecutor, Begin, BeginTx, Ping, HandleError
- Component — lifecycle.Component + observability.Checkable + Provider + Stats()
- UnitOfWork — Do(ctx, fn)

Implementation:
- New(logger, cfg) Component — pool not created until OnInit
- OnInit: pgxpool.NewWithConfig with duration parsing; 30s timeout
- OnStart: PING with 5s timeout; logs "postgres: connected"
- OnStop: pool.Close(); logs "postgres: closing pool"
- GetExecutor: returns active Tx from context (ctxTxKey) or pool; nil-safe
- Begin/BeginTx: wraps pgx.TxOptions; wrapped in xerrors on error
- HealthCheck: delegates to Ping; Priority LevelCritical
- Stats() *pgxpool.Stat — zero value when pool uninitialized
- NewUnitOfWork(logger, provider) UnitOfWork — Begin+inject+commit/rollback
- HandleError: UniqueViolation→ErrAlreadyExists, ForeignKey/Check→ErrInvalidInput,
  pgx.ErrNoRows→ErrNotFound, all others→ErrInternal

Config (EINHERJAR_PG_* env vars):
  Host, Port(5432), User, Password, Name, SSLMode(disable), Timezone(UTC),
  MaxConns(5), MinConns(2), MaxConnLifetime(1h), MaxConnIdleTime(30m),
  HealthCheckPeriod(1m)

- Component interface embeds observability.Identifiable; identifiable.go implements
  ModulePath and ModuleVersion via runtime/debug.ReadBuildInfo() — prints in launcher banner
