ci: repair publisher access and Dependabot required statuses

[coisa]

The isolated per-version publisher introduced by DevTools #362 needs actions: read in the caller's permission ceiling. GitHub validates this ceiling even when publication is disabled, so the current caller would fail before starting its jobs after adopting that workflow.

This grants read access to workflow job metadata. The shared workflow keeps test execution jobs at contents: read, actions: none and statuses: none; it reserves status writes for the separate publisher.

Validation: actionlint .github/workflows/tests.yml and git diff --check passed. A controlled GitHub caller with the old ceiling failed before creating jobs (negative case); changing only Actions read permission made the same pinned reusable workflow succeed (control). Library code, Dash artwork and README content are untouched. Merge this caller compatibility update before DevTools #362.

The optional .github/workflows/test-statuses.yml bridge handles Dependabot push lifecycle events from the default branch, using verified GitHub Run/Jobs metadata without checkout, caches, artifacts or caller code. Active attempts reset pending; completed attempts publish actual terminal results. The final code prevents old successes after full-rerun prerequisite failures, closes missing matrix jobs in failed/canceled runs as failures, preserves legitimate partial retries, rejects additional observed versions, and rechecks source metadata before every POST. The complete PHP 8.3/8.4/8.5 contract is explicitly configured for this repository; normal dev-tools:sync does not auto-install the optional source template. PHP 8.4 and 8.5 each passed 130 scenarios / 1,130 assertions (2,260 total). Real lifecycle activation awaits default-branch installation. The test caller's existing Statuses-write ceiling is retained; Actions-read is added for the isolated shared publisher. Deploy this compatibility PR before dev-tools#362, then deploy the ten newly enabled library callers.

Walkthrough

The pull request adds a workflow that verifies completed Dependabot test runs and publishes commit statuses for PHP 8.3, 8.4, and 8.5. It grants the test workflow Actions read permission, updates the changelog, and changes the wiki submodule pointer.

Changes

Dependabot status publication

Layer / File(s)	Summary
Workflow setup and permissions .github/workflows/test-statuses.yml, .github/workflows/tests.yml, CHANGELOG.md	The new workflow handles eligible Dependabot push runs and configures status-publishing permissions and PHP versions. The test workflow adds Actions read permission. The changelog records the changes.
Source run validation .github/workflows/test-statuses.yml	The workflow validates inputs and source-run metadata. It checks matching runs and skips publication when the source run is incomplete or superseded.
Job result validation and status publication .github/workflows/test-statuses.yml	The workflow validates completed job results for each PHP version, then publishes a success or failure commit status.

Wiki submodule pointer

Layer / File(s)	Summary
Wiki reference update .github/wiki	The submodule pointer changes from commit 44f2a6acd0fcce008914765e250b2fb56ec83189 to e5558a0801a211037754a06b4ce68fc61331cbfb.

Merge Risk: 🟡 Moderate · up to a3fc6

The new Dependabot status publisher can sometimes skip posting the required statuses for the latest test run on a commit. When that happens, Dependabot pull requests stay blocked until someone reruns the workflow manually. Adjust the concurrency handling before merging, or explicitly accept this behavior.

_{A rabbit checks each version’s run,
Then marks the commit when checks are done.
Three PHP paths pass through the gate,
Fresh results set each status straight.
The wiki pointer hops along,
And I nibble changelog crumbs for song.}
