runtime: prepend zsh fork bin dir to PATH

Summary:
- prepend the configured zsh fork executable directory to PATH for zsh-fork shell-command and unified-exec launches
- preserve that PATH value through shell snapshot wrapping so #!/usr/bin/env zsh can resolve to the packaged fork
- cover duplicate PATH entries and snapshot preservation in codex-core runtime tests

Test Plan:
- just fmt
- cargo test -p codex-core apply_zsh_fork_path_prepend
- cargo test -p codex-core maybe_wrap_shell_lc_with_snapshot_preserves_zsh_fork_path_prepend
- just fix -p codex-core

Notes:
- cargo test -p codex-core currently aborts in unrelated thread_manager::tests::resume_and_fork_do_not_restore_thread_environments_from_rollout with a stack overflow; rerunning that single test reproduces the same stack overflow.

+name: update-v8-version
+description: Update Codex's pinned `v8` / `rusty_v8` versions, validate the release-candidate path, and investigate failed V8 canary or artifact builds. Use when asked to bump V8, update `rusty_v8` artifacts, prepare or validate a V8 release candidate, check `v8-canary`, or diagnose why a V8 version update no longer builds.
+---
+
+# Update V8 Version
+
+## Core Workflow
+
+1. Read `third_party/v8/README.md` and follow its version-bump sequence. Treat
+   that document as the release-process source of truth.
+2. Inspect and update the concrete repo surfaces that carry the pin:
+   - `codex-rs/Cargo.toml`
+   - `codex-rs/Cargo.lock`
+   - `MODULE.bazel`
+   - `third_party/v8/BUILD.bazel`
+   - `third_party/v8/README.md`
+   - the matching `third_party/v8/rusty_v8_<version>.sha256` manifest when the
+     remaining prebuilt inputs change
+3. Keep the existing checksum helpers in the loop:
+
+   ```bash
+   python3 .github/scripts/rusty_v8_bazel.py update-module-bazel
+   python3 .github/scripts/rusty_v8_bazel.py check-module-bazel
+   python3 -m unittest discover -s .github/scripts -p test_rusty_v8_bazel.py
+   ```
+
+4. Validate the release-candidate path before broadening the work:
+   - Prefer checking the `v8-canary` CI result for the candidate branch or PR
+     when one exists, using GitHub check tooling or `gh` as appropriate.
+   - If CI is unavailable or the user asked for a local-only check, run the
+     closest local validation that is practical for the changed surface and say
+     explicitly that it is a local substitute, not the full hosted canary.
+5. If the canary path passes, stop there. Summarize the result and encourage the
+   user to commit the candidate changes or proceed with the release flow they
+   requested. Do not publish tags, releases, or pushes unless the user asked.
+
+## Failure Path
+
+Enter this path only when the canary or local build path fails.
+
+1. Capture the failing target, workflow job, and first actionable error.
+2. Compare the currently pinned version with the target version at the relevant
+   upstream tag or SHA. Inspect both:
+   - `denoland/rusty_v8`
+   - upstream V8 source at the target Bazel-pinned version
+3. Track build-relevant deltas rather than broad source churn:
+   - generated binding layout changes
+   - archive or asset naming changes
+   - GN/Bazel target changes
+   - custom libc++ / libc++abi / llvm-libc inputs
+   - sandbox or pointer-compression feature relationships
+   - patch hunks in `patches/` that no longer apply or no longer match upstream
+4. Trace each failing delta back into Codex's build graph:
+   - `MODULE.bazel`
+   - `third_party/v8/BUILD.bazel`
+   - `.github/scripts/rusty_v8_bazel.py`
+   - `.github/workflows/v8-canary.yml`
+   - `.github/workflows/rusty-v8-release.yml`
+5. Update only the pieces required to restore the target version's build and
+   artifact contract. Keep patch explanations and doc changes close to the
+   affected files.
+6. Re-run the focused validation. If it becomes green, return to the normal
+   workflow and stop with a concise summary plus the remaining release step.
+
+## Reporting
+
+- Say whether validation came from hosted `v8-canary` or from a local
+  substitute.
+- Distinguish "version bump complete" from "release published".
+- When blocked, report the upstream delta that matters, the Codex file it hits,
+  and the next concrete fix to try.
