test(office): align Python support contract with PR matrix

[seonghobae]

Problem

Protected main@a40b9489665bed7d95af619a6079b9c51cab299a already contains the #401 queue-fan-out change: the Office job runs only Python 3.14 for pull_request, while protected pushes retain the advertised 3.11–3.14 matrix. The retained repository contract still parses only a literal static list and therefore no longer describes the live workflow it is supposed to police.

This is a test-contract repair for already-integrated workflow truth. It does not change .github/workflows/ci.yml, the supported Python range, package metadata, dependencies, Office runtime behavior, or release policy.

RED → GREEN

RED on protected main: office/tests/test_python_support_contract.py requires python-version: [..] and exact equality to all four supported minors, but the protected workflow now uses the event-dependent expression ${{ github.event_name == 'pull_request' && fromJSON('["3.14"]') || fromJSON('["3.11", "3.12", "3.13", "3.14"]') }}. The structural contract cannot parse that current authority.

Candidate GREEN 378e03078a90f18c48317673344e4f1adb11ec8f changes only the contract test. It requires the exact event-sensitive shape, pins pull-request admission to the newest supported minor, and independently pins protected-push coverage to the complete advertised 3.11–3.14 set. The runner-image and release-workflow contracts remain unchanged.

This delta was discovered while reviewing #403 and is split into this repository-contract owner lane so the collaboration PR can be evaluated relative to a narrow prerequisite rather than permanently owning unrelated Office CI semantics.

Ready status admits this complete candidate to independent review and exact-head Checks. Terminal applicable CI/security evidence and a qualifying independent current-head review remain merge gates, not prerequisites to review admission. No predecessor result, no-op retrigger, self-approval, force update, destructive rebase, or workflow-gate weakening is accepted.

Merge Risk: 🔵 Low · up to 378e0

The Python CI contract test can pass even when a matrix branch includes unsupported extra values, allowing unintended CI coverage changes to go undetected. Parsing and comparing the complete arrays would make the contract enforce the intended versions.

extracting only entries matching the Python-version regex. Preserve validation
