feat: add muse apply command — apply .patch files to working tree

Implements _parse_patch, _apply_hunk, register, and run. - Parses unified diff (with mail-format header stripping) - Handles --check (validate without writing), --json output - Rejects path traversal and .muse/ internal paths - Supports format-patch → apply round-trip - 16 tests: unit, integration, security, stress — all green
