v1.3.0 — manifest_cache staleness check + build.dist.properties sync

Added

• cwm-verify detects and rebuilds stale manifest_cache. Each row in
  #__extensions carries a manifest_cache JSON column that Joomla
  populates on install and update. When an extension's install
  scriptfile update() doesn't run cleanly, that column drifts away
  from the source manifest XML — visible to users as
  mb_strtolower(null) deprecation warnings in Joomla 6's manage view.
  • ExtensionVerifier::parseManifestXml() reproduces Joomla's
    Installer::parseXMLInstallFile() shape so cwm-verify can build
    the canonical cache JSON.
  • ExtensionVerifier::compareManifestCache() checks the four fields
    the manage view actually reads (name, version, description,
    author) — other fields are informational and not worth surfacing
    as drift.
  • cwm-verify --target test now reports STALE: <name> manifest_cache — version: 'old' → 'new' per drifted extension.
  • cwm-verify --target test --fix UPDATEs the row with rebuilt JSON
    directly — no extension reinstall required.
  • Applies to self extensions AND CWM dep extensions installed via
    path repositories (expectedFromPackages() resolves the source
    manifest from each dep's joomlaLinks tuple).
• cwm-sync-configs distributes build.dist.properties to consumers.
  Each consuming project gets an auto-managed copy of cwm-build-tools'
  templates/build.properties.tmpl, headed by a marker comment telling
  developers to edit the upstream template rather than the local file.
  Schema changes to build.properties (the role field added in
  v1.1.0, the [paths] block added in v1.2.0) now propagate to every
  consumer on the next composer cwm-sync-configs run rather than
  silently drifting.

Migration

Per-repo:

1. composer require --dev cwm/build-tools:^1.3
2. composer cwm-sync-configs — refreshes build.dist.properties
   from the upstream template (committed change, review the diff).
3. Optionally composer cwm-verify --target test --fix against a
   live install with stale extension caches.
