📝 docs(tsl): clarify syntax constraints and enhance test infrastructure

- Add TSF file naming constraint to syntax/02_core_model.md
- Clarify semicolon rules: syntax facts vs style preferences
- Separate control flow end semicolon rules (syntax allows both)
- Add function body semicolon requirements to syntax/05_functions_and_calls.md
- Move style preferences to code_style.md (control flow end semicolons)
- Remove cross-references from syntax docs to maintain independence
- Enhance Gitea workflow emoji for better CI output readability
- Fix CI test path from tests/ to test/
- Organize agent test results under test/agent/result/ directory
- Add complete Chinese translation of test cases (test_cases_zh.md)
- Clean up .gitignore to use unified test/agent/result/ directory
- Remove obsolete agent test artifacts (REPORTS_LOCATION.md, old results)
