* fix(sdk): harden query layer for PR review (paths, locks, CLI, ReDoS)

- resolvePathUnderProject: realpath + relative containment for frontmatter and key_links

- commitToSubrepo: path checks + sanitizeCommitMessage

- statePlannedPhase: readModifyWriteStateMd (lock); MUTATION_COMMANDS + events

- key_links: regexForKeyLinkPattern length/ReDoS guard; phase dirs: reject .. and separators

- gsd-sdk: strip --pick before parseArgs; strict parser; QueryRegistry.commands()

- progress: static GSDError import; tests updated

* feat(sdk): query follow-up — tests, QUERY-HANDLERS, registry, locks, intel depth

Made-with: Cursor

* docs(sdk): use ASCII punctuation in QUERY-HANDLERS.md
