fix: emit Cursor front matter for synced Flutter AI rules profiles

[Wreos]

Motivation

• Synced official Flutter AI rule profiles were written with only an HTML comment header so the active profile file could not be auto-attached to Dart/Flutter files; adding Cursor rule front matter enables automatic application and profile switching.

Description

• Update scripts/sync_official_flutter_ai_rules.sh to prepend YAML front matter (description, alwaysApply, globs) before the synced content for each generated .mdc profile.
• Add the same YAML front matter to the checked-in synced artifacts under rules/official/ (flutter-ai-rules-10k.mdc, flutter-ai-rules-4k.mdc, flutter-ai-rules-1k.mdc).
• Add YAML front matter to the active profile copy at rules/flutter-official-ai-rules.mdc so it is auto-attached for lib/**/*.dart / test/**/*.dart / **/*.dart globs.

Testing

• bash -n scripts/sync_official_flutter_ai_rules.sh succeeded (syntax check passed).
• scripts/sync_official_flutter_ai_rules.sh 4k was attempted but failed in this environment due to upstream raw.githubusercontent.com returning HTTP 403, so full network fetch could not be exercised here.
• Verified via automated inspection that rules/official/*.mdc and rules/flutter-official-ai-rules.mdc now start with the expected YAML front matter (checked with sed/head).

Restrict auto-attach metadata to the active profile

Adding globs front matter in download_rule() makes every generated file in rules/official/ auto-match Dart files, so the plugin can apply 10k/4k/1k simultaneously instead of honoring the selected active copy. This conflicts with the repository’s own active-profile contract (docs/flutter-ai-rules-sync.md describes rules/flutter-official-ai-rules.mdc as the active profile) and can cause duplicated/conflicting guidance plus unnecessary token overhead whenever Dart files are opened.

Summary

• Addressed the review feedback by removing globs emission from download_rule(), so generated profile files under rules/official/ no longer auto-attach themselves to Dart files. This keeps those files as neutral synced artifacts. scripts/sync_official_flutter_ai_rules.shL33-L47
• Updated the script’s active-profile step to inject globs only when writing rules/flutter-official-ai-rules.mdc, preserving the active-profile contract while keeping auto-attach behavior on the selected profile only. scripts/sync_official_flutter_ai_rules.shL56-L67
• Updated the checked-in synced artifacts (10k, 4k, 1k) to remove globs from their front matter, matching the corrected behavior. rules/official/flutter-ai-rules-10k.mdcL1-L4 rules/official/flutter-ai-rules-4k.mdcL1-L4 rules/official/flutter-ai-rules-1k.mdcL1-L4
• Confirmed the active rule file still includes globs front matter. rules/flutter-official-ai-rules.mdcL1-L5
• Committed on the current branch as 56978eb and created a follow-up PR via the make_pr tool.

Testing

• ✅ bash -n scripts/sync_official_flutter_ai_rules.sh
• ✅ for f in rules/official/flutter-ai-rules-10k.mdc rules/official/flutter-ai-rules-4k.mdc rules/official/flutter-ai-rules-1k.mdc rules/flutter-official-ai-rules.mdc; do echo '---' $f; sed -n '1,8p' $f; done
