v1.2.10

Release v1.2.10

A robustness fix for the Quant-lint pass: a pathologically deep source file no
longer crashes the quality loop.

Fixed

• analyse_quant_lint_from_files could crash on a pathologically deep AST.
  Every Quant-lint rule (Q001–Q006) walks the tree with a recursive
  ast.NodeVisitor, so a single file with a many-hundred-branch elif chain
  (or a long chained arithmetic expression) could exceed Python's recursion
  limit mid-traversal and raise an uncaught RecursionError — taking down the
  whole quality-loop invocation (which gates on passes = not issues). The
  per-file analysis is now guarded so one pathological file degrades gracefully
  (skipped) instead of sinking the batch, mirroring the existing OSError
  guard in the directory walk. Found by an adversarial local probe of the
  v1.2.9 rules (~140 probes; no other issue surfaced — no false positives, no
  missed true positives).

Validation

• pytest: 3500 passed, 2 skipped.
