feat(6243): move_path carries a moved path's snippets with its shapes

Snippet locations are keyed by path too, so a snippet recorded under a
moved directory reads `missing` at its next check. The tool is now
move_path(project_id, from_path, to_path). It moves the ledger rows as
before, and re-paths the project's snippet locations under from_path
through update_snippet, so each body and its indexed mirror stay one
record. A snippet the caller can only read is listed in
snippets_read_only. The tool refuses only when nothing at all is recorded
under from_path. The path test is the one snippets already uses
(_path_touches), and the plugin version is minted for the skill edit.
