Route apply_patch through the environment filesystem (#17674 )

## Summary
- route apply_patch runtime execution through the selected Environment
filesystem instead of the local self-exec path
- keep the standalone apply_patch command surface intact while restoring
its launcher/test/docs contract
- add focused apply_patch filesystem sandbox regression coverage

## Validation
- remote devbox Bazel run in progress
- passed: //codex-rs/apply-patch:apply-patch-unit-tests
--test_filter=test_read_file_utf8_with_context_reports_invalid_utf8
- in progress / follow-up: focused core and exec Bazel test slices on
dev

## Follow-up under review
- remote pre-verification and approval/retry behavior still need
explicit scrutiny for delete/update flows
- runtime sandbox-denial classification may need a tighter assertion
path than rendered stderr matching

Stabilize exec-server filesystem tests in CI (#17671 )

## Summary\n- add an exec-server package-local test helper binary that
can run exec-server and fs-helper flows\n- route exec-server filesystem
tests through that helper instead of cross-crate codex helper
binaries\n- stop relying on Bazel-only extra binary wiring for these
tests\n\n## Testing\n- not run (per repo guidance for codex changes)

Run exec-server fs operations through sandbox helper (#17294 )

## Summary
- run exec-server filesystem RPCs requiring sandboxing through a
`codex-fs` arg0 helper over stdin/stdout
- keep direct local filesystem execution for `DangerFullAccess` and
external sandbox policies
- remove the standalone exec-server binary path in favor of top-level
arg0 dispatch/runtime paths
- add sandbox escape regression coverage for local and remote filesystem
paths

## Validation
- `just fmt`
- `git diff --check`
- remote devbox: `cd codex-rs && bazel test --bes_backend=
--bes_results_url= //codex-rs/exec-server:all` (6/6 passed)

Add sandbox support to filesystem APIs (#16751 )

## Summary
- add optional `sandboxPolicy` support to the app-server filesystem
request surface
- thread sandbox-aware filesystem options through app-server and
exec-server adapters
- enforce sandboxed read/write access in the filesystem abstraction with
focused local and remote coverage

## Validation
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-exec-server file_system`
- `cargo test -p codex-app-server suite::v2::fs`

[codex] Migrate apply_patch to executor filesystem (#17027 )

- Migrate apply-patch verification and application internals to use the
async `ExecutorFileSystem` abstraction from `exec-server`.
- Convert apply-patch `cwd` handling to `AbsolutePathBuf` through the
verifier/parser/handler boundary.

Doesn't change how the tool itself works.

Add cached environment manager for exec server URL (#15785 )

Add environment manager that is a singleton and is created early in
app-server (before skill manager, before config loading).

Use an environment variable to point to a running exec server.

Refactor ExecServer filesystem split between local and remote (#15232 )

For each feature we have:
1. Trait exposed on environment
2. **Local Implementation** of the trait
3. Remote implementation that uses the client to proxy via network
4. Handler implementation that handles PRC requests and calls into
**Local Implementation**
