v0.10.7

Fixed

• Published the shared template parser crate so masterror-derive no longer
  depends on a workspace-only package when uploaded to crates.io.

Documentation

• Added a dedicated README for masterror-template describing installation,
  parsing examples and formatter metadata for crates.io readers.

Tests

• Added regression coverage for long classifier needles to exercise the
  heap-allocation fallback.

Changed

• Added an owning From<AppError> conversion for ErrorResponse and updated the
  Axum adapter to use it, eliminating redundant clones when building HTTP error
  bodies.
• Precomputed lowercase Turnkey classifier needles with a stack-backed buffer
  to remove repeated transformations while keeping the common zero-allocation
  path for short patterns.
• Bumped masterror-derive to 0.6.6 and masterror-template to 0.3.6 so
  downstream users rely on the newly published parser crate.
