jif-oai ba57aab13a feat: dedicated goal DB (#23300) 
## Why

Thread goals are moving toward extension-owned runtime behavior, but
their persisted state was still stored in the shared state database.
This makes the goal store harder to isolate and keeps future storage
splits tied to ad hoc runtime plumbing.

This PR gives goals their own SQLite database while keeping the existing
`StateRuntime` entry point. The goal is to make this the pattern for
adding more dedicated runtime databases later.

This also reduce load on existing DB and reduce contention

## Limitation
Thread preview from goal is not supported anymore. I'm looking into this
[EDIT]: solved

## What changed

- Added a dedicated `goals_1.sqlite` database with its own
`goals_migrations` directory.
- Moved `thread_goals` creation into the goals DB migration set.
- Dropped the old `thread_goals` table from the main state DB with a
normal state migration. There is intentionally no backfill for existing
goal rows.
- Changed `GoalStore` to be backed only by the goals DB pool.
- Removed the old goal-write side effect that filled empty
`threads.preview` values from the goal objective.
- Added shared runtime DB path metadata so startup, telemetry, `codex
doctor`, and repair handling can include future DBs without bespoke path
lists.
- Updated Bazel compile data so the new goals migration directory is
available to `sqlx::migrate!`.

## Verification

- `cargo check --tests -p codex-state -p codex-cli -p codex-core -p
codex-app-server`
- `just fix -p codex-state`
- `just fix -p codex-cli`
- `just fix -p codex-app-server`
