fix: No forge compile verification in transpiler CI (#904)

- test_transpiler_clamping.sh: add Test 11 that runs forge build on the
  valid Solidity output from Test 6; fails if the transpiled contract
  does not compile (regression guard for #900)
- test_inject_extraction.sh: add SCRIPT_DIR, then Test 5 that transpiles
  optimizer_seed.push3 and runs forge build on the generated contract;
  ensures the full push3→Solidity→compile pipeline stays green
- .woodpecker/ci.yml: add transpiler-tests step that installs npm deps
  and runs both test scripts with forge on PATH
