Optimized changeindex and AST, vue support, better defaults and skill, MCP hot reload

[zinvob]

Detecting files is very slow on big repo's, added support for a change index. On initial build, it will create a changeindex.json file (filename, local changedate, size and hash) in same folder as graph.json. On subsequent build update, it will first check against the index and only do hash compute if changed local date. Also removed --update as it is redundant.

Cleaned up the skill for better Claude usage to make sure it does not try to load the complete graph.

Cleaned up defaults to only create files used by Claude as default, and prepare graphify-rs-out inside repo folder instead of a user folder for better access from Claude (just add to git ignore).

Added support for .vue files.

On local tested repo, speed for detect went from minutes to couple of seconds.

Optimized AST extract loop for AST extract speedup.

Fixed MCP server to auto refresh when graph.json changes from a build.

Pull request overview

This PR improves build performance on large repositories by introducing an on-disk change index for faster detection, removing the redundant --update flag, and tightening defaults to produce only Claude-relevant outputs by default.

Changes:

• Added changeindex.json-backed detection (detect_fast) and build short-circuiting when no content changed.
• Changed default output directory to graphify-rs-out/ under the project root and narrowed default export formats to json,report.
• Updated installer/skill docs for the new defaults and improved semantic extraction handling of cache hits.
