fix: No CI pipeline coverage for push3-evolution or push3-transpiler tests (#563)

Add evolution-tests step to Woodpecker CI pipeline. The transpiler-tests
step already existed; the new step runs push3-evolution's vitest suite
and triggers on changes to either tools/push3-evolution or
tools/push3-transpiler (since evolution imports the transpiler's parser).
