fix(deployment): only block files with explicit confidential markers, not filename patterns

- Removed filename pattern checks (session-handoff, draft, etc.)
- Now only blocks files with content markers: [INTERNAL], [CONFIDENTIAL], [DO NOT PUBLISH]
- Allows session handoff and internal documentation in docs/ directory
- Still blocks actual credentials and sensitive content

Rationale: Filename patterns were too broad and blocked legitimate internal documentation.
Session handoffs are fine in docs/ as long as they don't contain actual sensitive data.
