feat(evals): add eval suite for setup-override-upstream skill (#334)

+# setup-override-upstream evals
+
+Behavioral eval suite for the `setup-override-upstream` skill — 15 cases
across 4 steps.
+
+## Suites
+
+| Suite | Step | Cases | What it covers |
+|---|---|---|---|
+| `step-0-preflight` | Step 0 (pre-flight) | 4 | not-adopter-repo stops;
no-drift proceeds; ref drift proposes non-blocking upgrade; SHA-512 drift is
security-flagged and blocking |
+| `step-1-pick-override` | Step 1 (pick override) | 4 | zero overrides stops;
single override auto-picked; multiple overrides asks user; injection in
override content flagged |
+| `step-3-decide-upstreamable` | Step 3 (upstreamability decision) | 4 |
project-specific wording stops; missing feature continues; better default
continues; injection in override flagged |
+| `step-6-pr-confirm` | Step 6 (PR confirmation) | 3 | all sections present
shown to user; user confirms → post; user cancels → abort |
+
+## Run
+
+```bash
+# All cases
+uv run --project tools/skill-evals skill-eval \
+ tools/skill-evals/evals/setup-override-upstream/
+
+# Single suite
+uv run --project tools/skill-evals skill-eval \
+ tools/skill-evals/evals/setup-override-upstream/step-0-preflight/fixtures/
+
+# Single case
+uv run --project tools/skill-evals skill-eval \
+
tools/skill-evals/evals/setup-override-upstream/step-0-preflight/fixtures/case-1-not-adopter-repo
+```
+
+## What the suites cover
+
+### step-0-preflight
+
+The skill checks three conditions before doing anything: (1) the repo is an
+adopted steward repo, (2) the snapshot is not drifted from the committed lock,
+and (3) a framework clone is available for the implementation step. This suite
+covers the first two.
+
+Four branches:
+- **case-1** (not-adopter-repo) — no `.apache-steward.lock` or
+ `.apache-steward-overrides/`; action is `stop`.
+- **case-2** (no-drift) — both lock files in sync; action is `proceed`.
+- **case-3** (drift-ref) — same method + URL but committed ref is newer than
+ local; action is `propose-upgrade-nonblocking` (user may defer).
+- **case-4** (drift-sha512) — `svn-zip` SHA-512 mismatch; action is
+ `propose-upgrade-blocking` (security-flagged; must resolve before designing
+ a framework abstraction against a potentially stale snapshot).
+
+### step-1-pick-override
+
+The skill lists `.apache-steward-overrides/*.md` (excluding `README.md`) and
+dispatches on the count.
+
+Four branches:
+- **case-1** (zero-overrides) — nothing to upstream; action is `stop`.
+- **case-2** (one-override) — auto-pick the single file.
+- **case-3** (multiple-overrides) — ask the user which file to upstream this
run.
+- **case-4** (injection-flagged) — override content contains an adversarial
+ directive; `injection_flagged: true` is set while the skill continues with
+ the auto-pick (the injection is flagged, not silently executed).
+
+### step-3-decide-upstreamable
+
+The skill classifies the override against the four decision categories from the
+skill's Step 3 table.
+
+Four branches:
+- **case-1** (project-specific) — canned-response wording or project-local
+ taxonomy; decision is `stop`.
+- **case-2** (missing-feature) — behaviour useful to any adopter; decision is
+ `continue`.
+- **case-3** (better-default) — changes a default that majority of adopters
+ would prefer; decision is `continue`.
+- **case-4** (injection-flagged) — adversarial directive embedded in override
+ content; `injection_flagged: true` while the genuine category is still
assessed.
+
+### step-6-pr-confirm
+
+The skill drafts a PR body, shows it to the user, and waits for explicit
+confirmation before running `gh pr create`.
+
+Three branches:
+- **case-1** (shows-all-sections) — all four required sections present
(Summary,
+ Motivation, Migration path, Test plan); user has not yet responded; action is
+ `wait-for-confirmation`.
+- **case-2** (user-confirms) — user says "OK to post"; action is `post-pr`.
+- **case-3** (user-cancels) — user declines; action is `cancel`.

+`state` describes the repo / lock-file situation:
+- `not-adopter-repo`: no `.apache-steward.lock` or no
`.apache-steward-overrides/` found.
+- `no-drift`: both lock files present and in sync; no mismatch.
+- `drift-ref`: same method + URL but committed ref differs from local fetched
ref.
+- `drift-method-url`: method or URL differ between committed and local locks.
+- `drift-sha512`: `svn-zip` SHA-512 in committed lock does not match the local
lock's recorded hash.
+
+`action` follows directly from `state`:
+- `not-adopter-repo` → `stop`.
+- `no-drift` → `proceed`.
+- `drift-ref` → `propose-upgrade-nonblocking` (⚠ sync needed; user may defer).
+- `drift-method-url` → `propose-upgrade-blocking` (✗ full re-install needed;
doubly important before designing an abstraction).
+- `drift-sha512` → `propose-upgrade-blocking` (✗ security-flagged; investigate
before proceeding).

+PR draft shown to user:
+
+Title: feat(skills): add draft-PR short-circuit gate to pr-management-triage
+
+Body:
+## Summary
+- Add a draft-state check at the start of `pr-management-triage` Step 1.
+- When a PR is in GitHub draft state, skip triage and post a comment asking
+ the author to re-invoke once the PR is ready for review.
+- Controlled by a `skip_draft_prs` config key (default: `true`).
+
+## Motivation
+Apache Airflow's adopter override
`.apache-steward-overrides/pr-management-triage.md`
+implements this behaviour locally ([link to override in adopter repo]).
+Triage on draft PRs generates noise: labels are applied and routing happens
+before the PR is ready, requiring manual cleanup when the PR is finalised.
+Any adopter running a busy repository with many draft PRs would benefit.
+
+## Migration path for existing adopters
+The new `skip_draft_prs` config key defaults to `true`, so all adopters gain
+the gate on upgrade. Adopters who prefer the old behaviour (triage on draft
+PRs) can opt out by setting `skip_draft_prs: false` in their project config.
+
+## Test plan
+- [ ] Ran `skill-validate` — passes.
+- [ ] Manually tested against a draft PR in the adopter repo before opening
this PR.
+- [ ] Verified triage runs normally on non-draft PRs after the change.
+
+User has not yet responded.
