fix(mcp): add project detection from memory:// URLs in edit_note and delete_note

edit_note and delete_note were missing detect_project_from_url_prefix()
which other tools (read_note, build_context, search_notes, read_content)
already use. This caused incorrect cloud routing when using memory://
URLs without an explicit project parameter in multi-project setups.

Fixes #664
