feat(backends): make PreferDevelopmentBackends install the development image as primary

When LOCALAI_PREFER_DEV_BACKENDS is set, install the -development image as the
primary backend URI (keeping the released image reachable as the first
fallback), instead of only reaching development as a download fallback when the
released image is missing. This lets an operator force backends built from the
development branch — e.g. to pick up a fix already on master before a release.

Threads PreferDevelopmentBackends through SystemState so InstallBackend can see
it, and reuses the same development-URI convention as the existing failure-path
fallback (released tag -> branch tag + dev suffix). The unexported developmentURI
helper is covered by a Ginkgo spec.

 The PostgreSQL image `quay.io/mudler/localrecall:v0.5.2-postgresql` is pre-configured with pgvector and ready to use.
 
+#### Connection safety timeouts (PostgreSQL only)
+
+The embedded vector store sets per-connection timeouts so a single stuck or corrupt index can never hold a lock indefinitely and stall every other collection operation. Safe defaults are applied automatically — you only need to set these to override them:
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `POSTGRES_LOCK_TIMEOUT` | `30s` | Bounds how long a statement waits to acquire a lock, so queued statements fail fast instead of piling up. Set `0`/`off` to disable. |
+| `POSTGRES_IDLE_IN_TRANSACTION_TIMEOUT` | `300s` | Reaps abandoned transactions that would otherwise pin locks. Set `0`/`off` to disable. |
+| `POSTGRES_STATEMENT_TIMEOUT` | _(unset)_ | Bounds total statement runtime, auto-aborting a wedged query. Off by default since a large vector index build can exceed any fixed limit; index builds are exempted, so it is safe to enable. |
+
+These are read directly from the LocalAI process environment by the embedded store (the same as `DATABASE_URL` and `HYBRID_SEARCH_*`).
+
