feat: /land-and-deploy first-run dry-run, staging-first, trust ladder

First run shows a dry run — detect deploy infrastructure, validate commands,
show what will happen — then confirm before proceeding. Staging-first option
when staging detected. Config decay: re-triggers dry run if deploy config
changes. Full wordsmithed copy for every user-facing message.

Key changes:
- Step 1.5: first-run dry-run with infrastructure validation table
- Step 3.5a-bis: inline review gate before deploy
- Step 4a/4b: merge queue + CI auto-deploy detection and messaging
- Step 5a: staging-first option with verify-then-promote flow
- Voice & Tone section: narrate-the-journey, teacher mode vs efficient mode
- Config fingerprinting: trust decays when deploy config changes
