Fix typo: KUETSU_DIR -> KUGETSU_DIR

Combines context dump/load feature with worktree lifecycle features:
- CONTEXT_DIR and ENABLE_CONTEXT_DUMP config
- Context functions: kugetsu_context_load/dump/update_message
- WORKTREE_CHECK_PR_STATUS config
- check_pr_status() and update_session_pr_url() functions
- set-pr and context commands
