fix: update stale references and restore silence safety net (PRI-974)

Post-inversion cleanup:

- executing-plans, subagent-driven-development: update Integration
  description from "Ensures isolated workspace" to "Detects workspace
  environment and offers worktree isolation on request"
- codex-tools.md: update step references (Step 0→1, Step 1→2)
- using-git-worktrees Step 2: restore "silence → ask once more" instead
  of "silence → work in place" to preserve safety net for confused users
