[Fix] Remove all emoji violations from code files

- Replaced emojis with ASCII text markers ([OK], [ERROR], [WARNING], etc.)
- Fixed 38+ violations across 20 files (7 Python, 6 shell scripts, 6 hooks, 1 API)
- All modified files pass syntax verification
- Conforms to CODING_GUIDELINES.md NO EMOJIS rule

Details:
- Python test files: check_record_counts.py, test_*.py (31 fixes)
- API utils: context_compression.py regex pattern updated
- Shell scripts: setup/test/install/upgrade scripts (64+ fixes)
- Hook scripts: task-complete, user-prompt-submit, sync-contexts (10 fixes)

Verification: All files pass syntax checks (python -m py_compile, bash -n)
