fix: add test suite for quality gate modules (#629)

34 tests covering both quality gate modules:

ci_automation_gate.py (17 tests):
- Trailing whitespace detection and auto-fix
- Missing final newline detection and fix
- JS/TS function length warnings (20 lines) and failures (50 lines)
- Python files excluded from JS function length check
- File type filtering (.py, .js, .ts checked; .md, .json skipped)
- Directory traversal with node_modules and .git exclusions
- Exit codes (0 for clean, 1 for failures)

task_gate.py (17 tests):
- Filter tag detection (EPIC, DO NOT CLOSE, PERMANENT, MORNING REPORT)
- Agent lane checking (no config, missing agent, present agent)
- Pre-task gate: issue not found, filter tags, assigned agents,
  existing PRs, clean pass
- Post-task gate: missing branch, naming convention warning,
  no commits failure
- Integration: gate runs on its own source files

Closes #629
