Revert: Remove ccw session management while keeping ccw cli exec

Selectively revert ccw session management commands back to commit 5114a94,
while preserving ccw cli exec improvements.

Changes:
- Session management commands (start, list, resume, complete): Full revert to bash commands
- execute.md: Full revert (only had ccw session changes)
- review.md: Reverted ccw session read, kept ccw cli exec
- docs.md: Reverted ccw session read/write, kept ccw cli exec
- lite-fix.md: Reverted ccw session init/read, kept other changes
- lite-plan.md: Reverted ccw session init/read, kept other changes
- lite-execute.md: No changes (kept ccw cli exec intact)
- code-developer.md: No changes (kept ccw cli exec intact)

All ccw session management operations replaced with bash commands.
All ccw cli exec commands preserved for unified CLI execution.
