v0.4.3

Added

• rename_symbol (.ts, .tsx, .js, .jsx) — the first write-capable
  tool. Resolves the symbol like find_references, then applies TypeScript's own
  findRenameLocations across every project file and writes the edits to disk in
  one call, returning the rewritten locations as a diff for review. Refuses the
  whole rename — no partial write — when any location falls outside the project
  (a .d.ts or node_modules declaration), and rejects an invalid or reserved
  new_name before the worker round trip.
• check_safe_to_delete (.ts, .tsx, .js, .jsx) — read-only. Answers
  "is any top-level declaration in this file referenced from another file?" in a
  single call, replacing a find_references sweep over every export. Returns
  safe: true only when nothing is used elsewhere, otherwise the blocking
  cross-file references.

Changed

• Agent-facing text (tool descriptions, the tool_handler instructions string,
  the packaged skill) is now held to a minimum-token bar, formalized as design
  constraint #4 in ARCHITECTURE.md and a repo-root CLAUDE.md for future
  contributors: this text is injected into a model's context on every call, so
  compact rows beat prose.
