fix(freebyrd): fix const shared_ptr reset and unused variable warnings

- Remove block.reset() in decodeAndTransform lambda — the shared_ptr
  is captured by value (const in non-mutable lambda), so reset() is
  invalid. Early return without reset is sufficient.
- Remove unused numRes and tilec variables in postProcess()

Fixes CI build failure on Ubuntu with GCC 13.
