v0.1.0

• Initial release.
• Framework: tool registry (method_tools_register), Tools → Method Tools admin page, Post_Tool base with targeting (block-editor post types, site-editor types, statuses, ID include/exclude), SQL-prefiltered candidate scan, dry run, batched apply through wp_update_post(), signed per-run backups with restore, REST API (method-tools/v1) and WP-CLI (wp method-tools).
• Offset-preserving block parser (Blocks\Block_Document) so tools rewrite only the blocks they target.
• Accordion Converter: core/accordion ⇄ method/accordion, independent of block registration (works before WordPress 6.9).
