Fix workflow duplication, resource leaks, and datetime timezone bugs

[Copilot]

CI workflows were running duplicate jobs on PRs. Codebase had resource leaks in SQLite connections and naive datetime usage causing timezone comparison failures.

Workflow

• Remove pull_request trigger from ci.yml (now push-only; pr-check.yml handles PRs)
• Add pip caching for consistency across workflows

Resource Management

Before:

conn = sqlite3.connect(db_file)
cursor = conn.cursor()
cursor.execute("SELECT COUNT(*) FROM features")
conn.close()  # Never called on exception
return count

After:

with sqlite3.connect(db_file) as conn:
    cursor = conn.cursor()
    cursor.execute("SELECT COUNT(*) FROM features")
    return count  # Connection auto-closed

Fixed 3 instances in progress.py.

Datetime Consistency

Issue: Mixed naive and UTC-aware datetimes cause TypeError on comparison.

Fixed: 6 instances across registry.py and parallel_orchestrator.py:

• datetime.now() → datetime.now(UTC)
• session_start_time: datetime = None → datetime.now(UTC) (prevents AttributeError)

Error Visibility

Added logging to 12 silent exception handlers:

• progress.py: Database ops, webhook failures
• prompts.py: Template loading, file copy failures
• server/routers/auth.py: Token revocation

Code Quality

• Auto-fixed 30 linting issues (imports, type annotations, deprecated patterns)
• Per-file ignores for print statements in CLI tools

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• cdn.jsdelivr.net
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

please fix workflow on my latest commit to main. also do debugging and refactor, find bug and fix but on my entire code
