refactor(commands): replace bash/jq operations with ccw session commands

- session/start.md: Replace find/mkdir/echo with ccw session list/init
- session/list.md: Replace find/jq with ccw session list/stats/read
- session/resume.md: Replace jq status updates with ccw session status
- session/complete.md: Replace jq/mv with ccw session archive
- execute.md: Replace session discovery with ccw session list/status
- code-developer.md: Replace jq context-package read with ccw session read

Benefits:
- Atomic operations (no temp files)
- Auto workspace detection (works from subdirectories)
- Auto session location detection (active/archived/lite)
- Status history auto-tracking for tasks
- Consistent error handling
