v0.12.1

Fixed

• audit-project orphan-hinter fd regression (#63) — 0.12.0 switched the
  PS-204 orphan-test hinter's file discovery from stdlib rglob to the Rust
  fd/fdfind tool with NO fallback, so audit-project hard-crashed with
  FdNotFoundError on any runner without fd (e.g. GitHub ubuntu-latest),
  turning the quality CI red ecosystem-wide. fd_find_files now keeps fd
  as the preferred fast path but, when it is absent, emits a loud warning
  (RuntimeWarning, "fd/fdfind not found on PATH — falling back to slower
  stdlib scan; install fd for speed") and falls back to a stdlib rglob
  walk so the audit runs to completion. No silent fallback, no hard crash by
  default.

Added

• audit.require-fd strict knob — a repo may opt into fail-loud-on-missing
  -fd via .scitex/dev/config.yaml audit.require-fd: true (or pyproject
  [tool.scitex_dev] audit.require_fd = true). When enabled and fd is
  absent, the orphan-hinter raises FdNotFoundError instead of falling back —
  for CI that wants to guarantee the fast path ran. The resolver mirrors
  is_mcp_parity_exempt's pyproject + config.yaml resolution.
