jif-oai 87bbfc50a1 feat: prevent double backfill (#11377 )

## Summary

Add a DB-backed lease to prevent duplicate `.sqlite` backfill workers
from running concurrently.

### What changed
- Added StateRuntime::try_claim_backfill(lease_seconds) that atomically
claims backfill only when:
  - backfill is not complete, and
  - no fresh running worker currently owns it.
- Updated backfill_sessions to use the claim API and exit early when
another worker already holds the lease.
- Added runtime tests covering:
  - singleton claim behavior,
  - stale lease takeover,
  - claim blocked after complete.
- Set backfill lease to 900s in production and 1s in tests.

### Why

This avoids duplicate backfill work and reduces backfill status churn
under concurrent startup, while preserving
current best-effort fallback behavior.

codex-core

This crate implements the business logic for Codex. It is designed to be used by the various Codex UIs written in Rust.

Dependencies

Note that codex-core makes some assumptions about certain helper utilities being available in the environment. Currently, this support matrix is:

macOS

Expects /usr/bin/sandbox-exec to be present.

When using the workspace-write sandbox policy, the Seatbelt profile allows writes under the configured writable roots while keeping .git (directory or pointer file), the resolved gitdir: target, and .codex read-only.

Linux

Expects the binary containing codex-core to run the equivalent of codex sandbox linux (legacy alias: codex debug landlock) when arg0 is codex-linux-sandbox. See the codex-arg0 crate for details.

All Platforms

Expects the binary containing codex-core to simulate the virtual apply_patch CLI when arg1 is --codex-run-as-apply-patch. See the codex-arg0 crate for details.
