ci: fail closed in umbrella result gate

[Kyzcreig]

Summary

• fail the umbrella job for cancelled and every result outside success / skipped
• fail when a classifier-required lane is skipped, including Python tests and lint
• move the evaluator into a pure tested script while preserving the compact needs-json output contract

Why

The previous evaluator only rejected literal failure. A cancelled dependency therefore passed the required All required checks pass context. It also accepted tests: skipped even when detect.outputs.python == 'true', so branch protection could go green without Python tests completing.

Verification

• scripts/run_tests.sh tests/ci — 175 passed
• scripts/run_tests.sh tests/ci/test_evaluate_needs.py — 23 passed
• pre-fix evaluator run — 16 failed, 5 passed, including cancellation and required-skip cases
• ruff check and ruff format --check
• actionlint .github/workflows/ci.yml
• direct CLI matrix: success=0, cancelled=1, Python-required tests skipped=1; all cases emitted the same compact needs-json shape

CI diagnosis:

• The new All required checks pass gate failed closed because tests and review-labels failed; that is the intended behavior of this PR.
• sast, secret_scan, lints, desktop E2E, docs, JS/TS, supply-chain, OSV, and the new evaluator's 23-test file passed.
• The sampled Python reds are inherited from main commit 11cffc4d5 (PR feat(kanban): CLI auto-subscribe knob + dispatch unwatched warning (fork-adapted from #80564) #470), not introduced here. On this PR branch and a detached clean fork/main control, the same two files produced the same result: 172 passed, 5 failed. The failures are in tests/hermes_cli/test_kanban_core_functionality.py and tests/hermes_cli/test_kanban_cli_dispatch_passthrough.py; this PR changes only .github/workflows/ci.yml, scripts/ci/evaluate_needs.py, and tests/ci/test_evaluate_needs.py.
• The review-label failure is the expected CI-sensitive-change gate: a reviewer must add ci-reviewed and rerun it after reviewing .github/workflows/ci.yml.

I am leaving the PR open for review rather than bypassing either red gate.

ci-reviewed applied by Apollo after hands-on verification of the gate's real behavior (not just a green test run).

Drove evaluate_needs() directly from the branch with synthetic needs payloads:

scenario	result
tests: cancelled	FAILS gate — "tests concluded 'cancelled'; expected 'success' or 'skipped'"
tests: skipped + detect.python == 'true'	FAILS gate — "classifier inconsistency: tests was skipped even though detect.outputs.python == 'true'"
tests: skipped + detect.python == 'false'	passes (correct — legitimate classifier skip)
all success	passes
tests: failure	FAILS gate

That's the fail-closed semantics this PR exists to add: the old evaluator only failed on result == 'failure', so a job CANCELLED by a runner outage (today's Actions incident class), concurrency eviction, or a manual cancel evaluated as green. Plus 23 unit tests green.

Reviewed against the .github/** sensitive-path policy: the change is confined to the umbrella evaluator's decision logic, the needs-json output shape is preserved for the comment assembler, and the deliberate comment-live/docker exclusions in needs: are untouched.
