fix(runtime): implement assert throws helpers

[andrewtdiz]

Summary

• implement synchronous assert.throws and assert.doesNotThrow for node:assert and node:assert/strict
• trap callback exceptions through Perry's native exception stack
• support regexp, built-in Error constructor, and shallow error-object matcher cases
• wire static/native lowering, callable exports, API manifest/docs, and runtime tests

Verification

• ./run_parity_tests.sh --suite node-suite --module assert --filter generated-message/throws-generated PASS
• ./run_parity_tests.sh --suite node-suite --module assert --filter errors/throws PASS 2/2
• ./run_parity_tests.sh --suite node-suite --module assert --filter errors/strict-throws-validation PASS
• ./run_parity_tests.sh --suite node-suite --module assert PASS threshold: 55 pass / 8 fail / 0 compile fail
• cargo test -p perry-runtime assert --lib PASS
• cargo test -p perry-codegen manifest_consistency --lib PASS
• bash scripts/regen_api_docs.sh PASS
• cargo fmt --all -- --check PASS
• git diff --check PASS
• jq empty test-parity/known_failures.json PASS

Residual full-suite assert failures are unrelated lanes: deep equality edge cases, async rejects, and CallTracker version skew. Full dynamic Error property storage is also left out of this slice.
