preamble: split 'checkpoint' routing rule into context-save + context-restore

scripts/resolvers/preamble.ts:238 is the source of truth for the routing
rules that gstack writes into users' CLAUDE.md on first skill run, AND
gets baked into every generated SKILL.md. A single 'invoke checkpoint'
line points at a skill that no longer exists.

Replace with two lines:
- Save progress, save state, save my work → invoke context-save
- Resume, where was I, pick up where I left off → invoke context-restore

Tier comment at :750 also updated.

All SKILL.md files regenerated via bun run gen:skill-docs.
