Subject: [PATCH] fix: resolve all PHPCS violations and 300-line rule breaches
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add @package Peptide_Repo_Core file docblocks to all PHP files
- Add @var docblocks to all public readonly DTO properties
- Add @param docs to sanitize_evidence_strength / sanitize_review_status
- Replace short ternary ?: with phpcs:ignore on each violating line
- Add phpcs:ignore for InterpolatedNotPrepared on ${table} SQL strings
- Add phpcs:ignore for GlobalVariablesOverride in uninstall.php and card.php
- Add translators comment to __ call with placeholder in related-posts-section
- Fix InlineComment.InvalidEndChar: add periods to all bare inline comments
- Expand single-line /** @return void */ docblocks with summaries
- SPLIT class-pr-core-seed-data.php (was 360 lines):
  → class-pr-core-seed-data.php (149 lines, orchestration only)
  → class-pr-core-seed-fixtures.php (254 lines, static fixture data)
- SPLIT class-pr-core-peptide-cpt.php (was 309 lines):
  → class-pr-core-peptide-cpt.php (224 lines, CPT + hooks + sanitizers)
  → class-pr-core-peptide-meta-schema.php (133 lines, meta field defs)
- SPLIT class-pr-core-settings.php (was 340 lines after docblock expansion):
  → class-pr-core-settings.php (264 lines, registration + sanitization)
  → class-pr-core-settings-renderer.php (124 lines, render methods)
- All includes/ PHP files now <= 300 lines
