Call `scrub_non_inheritable_env_vars` directly from each Git command path and
remove the redundant crate-local forwarding helper.

## Why
Model-reachable child processes should not inherit Codex launch context.
## What changed
- Treat `OPENAI_FEDERATION_RULE_ID` and `OPENAI_IDENTITY_TOKEN_FILE` as non-inheritable environment variables, with case-insensitive matching.
- Remove them after shell environment policy overrides and before spawning commands across execution, MCP, hooks, Git helpers, and remote helper processes.
## Testing
- Cover inherited and explicitly configured variants, including mixed-case names.
- Verify the variables are absent from real child environments and app-server command and process execution.

## Why
A repository can contain a tracked directory that Git implicitly treats as a bare
repository. Its configuration may select helpers such as `core.fsmonitor`, causing
Codex Git operations in that directory to execute repository-controlled code.
## What changed
- Pass `-c safe.bareRepository=explicit` to Codex-managed Git commands so they
reject implicitly discovered bare repositories.
- Continue to support repositories explicitly selected with `--git-dir` or
`GIT_DIR`.
## Testing
Add a regression test that clones a repository containing a tracked embedded Git
repository and verifies that guarded Git inspection rejects it without running
its configured filesystem monitor.

## What
- Internal Git helper commands now ignore configured hook directories
during repository bookkeeping.
## Why
- These helper flows should stay consistent even when a repository has
hook-directory configuration of its own.
## How
- Pass a command-local `core.hooksPath` override in the shared helper
path and the Git-info helper path.
- Add regressions for the baseline index rewrite flow and the metadata
status flow.
## Validation
- `cargo fmt --manifest-path
/Users/bookholt/code/codex/codex-rs/Cargo.toml --all --check`
- `cargo test --manifest-path
/Users/bookholt/code/codex/codex-rs/Cargo.toml -p codex-git-utils`
- `cargo test --manifest-path
/Users/bookholt/code/codex/codex-rs/Cargo.toml -p codex-core
test_get_has_changes_`
## Summary
- Remove `ghost_snapshot` / `GhostCommit` from the Responses API surface
and generated SDK/schema artifacts.
- Keep legacy config loading compatible, but make undo a no-op that
reports the feature is unavailable.
- Clean up core history, compaction, telemetry, rollout, and tests to
stop carrying ghost snapshot items.
## Testing
- Unit tests passed for `codex-protocol`, `codex-core` targeted undo and
compaction flows, `codex-rollout`, and `codex-app-server-protocol`.
- Regenerated config and app-server schemas plus Python SDK artifacts
and verified they match the checked-in outputs.
- create `codex-git-utils` and move the shared git helpers into it with
file moves preserved for diff readability
- move the `GitInfo` helpers out of `core` so stacked rollout work can
depend on the shared crate without carrying its own git info module
