Take the minimum PHP lint from the shared umbrella [ignore_release]

[snake14]

Description

Important

Depends on matomo-org/plugin-ci-workflows#14. Merging this before that lands would remove the check entirely rather than move it, so this stays a draft until #14 is merged.

.github/workflows/min-php-lint.yml is a byte-identical copy in three repositories — this one, plugin-ApiReference and plugin-SearchEngineKeywordsPerformance. Once #14 lands, the ci.yml umbrella calls the shared plugin-min-php-lint.yml, so keeping the local copy would run the same check twice under the same job name.

The shared workflow is a superset of this one:

• it derives the floor from this plugin's own composer.json and plugin.json instead of hardcoding 8.1, so it keeps tracking the declared minimum when that moves;
• it fails when the lint path exists but contains no PHP, which the local copy passes green — that is what a stale or mistyped path looks like;
• it follows a symlinked lint path, which the local copy would silently list as empty;
• it collects the file list before parsing, so a find that fails partway cannot leave a green check over a partial tree;
• it escapes % and newlines in annotations, so a multi-line parse error is not truncated to its first line.

It also corrects the remediation advice. The local copy says "Re-run the scoper", but matomo-scoper prefixes without downgrading, so re-running it changes nothing; the shared one points at the two things that do fix it — lower config.platform.php and re-resolve, or raise require.php if the declared floor is stale.

No behaviour is lost: the job keeps the same name, and this plugin's floor resolves to the same 8.1 the local copy hardcoded.

Issue No

No GitHub issue.

Steps to Replicate the Issue

1. Merge Lint scoped dependencies at the floor the plugin actually declares plugin-ci-workflows#14 and look at a pull request here.
2. Expected result: the minimum PHP lint runs once.
3. Actual result: it runs twice, once from the umbrella and once from the local copy.
