docs: make CONTRIBUTING and Makefile help match real verification gates (#4667)

CONTRIBUTING.md and the Makefile HEADER advertised nonexistent targets
(make clippy, make check) and claimed 'make pre-commit' runs
format + clippy + check + test, while .config/make/pre-commit.mak
actually runs fmt-check + guard scripts + quick-check with no clippy
and no tests. CONTRIBUTING.md also claimed the repository ships an
automated pre-commit git hook, but no hook is versioned.

- Replace phantom targets with the real ones (clippy-check,
  quick-check, compilation-check)
- Document exactly what pre-commit and pre-pr run, gate by gate,
  with an explicit note that pre-commit runs no clippy and no tests
- Point contributors to 'make pre-pr' as the full pre-PR gate
- Rewrite the git-hooks section to say hooks are optional and not
  versioned; setup-hooks only marks an existing hook executable

No make targets were added or changed; docs/help truth only.

+#### What `make pre-commit` and `make pre-pr` actually run
 
-This project includes a pre-commit hook that automatically runs before each commit to ensure:
+`make pre-commit` is the **fast** gate. It runs, in order
+(see `.config/make/pre-commit.mak`):
 
-- ✅ Code is properly formatted (`cargo fmt --all --check`)
-- ✅ No clippy warnings (`cargo clippy --all-targets --all-features -- -D warnings`)
-- ✅ Code compiles successfully (`cargo check --all-targets`)

+4. `logging-guardrails-check` — `./scripts/check_logging_guardrails.sh`
+5. `tokio-io-uring-check` — `./scripts/check_no_tokio_io_uring.sh`
+6. `doc-paths-check` — `./scripts/check_doc_paths.sh`
+7. `quick-check` — `cargo check --workspace --exclude e2e_test`
 
-#### Setting Up Pre-commit Hooks
+**`make pre-commit` does NOT run clippy and does NOT run any tests.**
+A green `make pre-commit` is not enough to open a pull request.
 
-Run this command once after cloning the repository:
+`make pre-pr` is the **full** gate: it runs all of the guard checks above,
+then `clippy-check` (`cargo clippy --all-targets --all-features -- -D warnings`)
+and `test` (shell script tests, workspace tests excluding `e2e_test`, and doc
+tests). Run `make pre-pr` before opening or updating a pull request — this is
+what CI enforces.
+
+### 🔒 Git Pre-commit Hooks (optional)
+
+Git hooks are **not** versioned in this repository, so a fresh clone has no
+active pre-commit hook. If you add your own `.git/hooks/pre-commit` (a good
+choice is a one-liner that runs `make pre-commit`), you can mark it executable
