docs: lead with the agent, demote deterministic-CLI from headline framing

[nahiyankhan]

Summary

• Reframe Ghost's positioning across CLAUDE.md, README, docs site, three skill bundles (ghost-drift, ghost-expression, ghost-fleet), and map.md so agents loading the project context lead with the right mental model: agents ship UI; it drifts; Ghost is the layer that gives them a canonical design language to follow.
• The "deterministic CLI + judgement in skills" dichotomy moves from headline copy to a footnote that points at INVARIANTS §1 and §4, where the underlying constraint actually lives. No architectural changes — every CLI verb is still pure, every recipe still runs in the host agent.
• Skill-bundle preambles now address the agent directly ("you do the reading, deciding, and writing; the CLI is the calculator you reach for") instead of editorializing on Ghost's CLI/LLM split.
• Patch-bumps ghost-drift and ghost-expression since their skill bundles are user-visible (changeset included).

The motivation: agents kept parroting "deterministic CLI" back as if it were the headline, because it was the first thing they read. The architecture is sound — the framing was over-indexed on the substrate and undersold the agent-native ethos.

Test plan

• CI: pnpm check (biome, typecheck, file-sizes, docs frontmatter, cli-manifest) + pnpm test + pnpm build
• Visual: skim docs site (/, /docs/getting-started, /docs/cli, /tools/map, /tools/fleet) for any awkward residual phrasing
• Read installed .claude/skills/ghost-drift/SKILL.md and .claude/skills/ghost-expression/SKILL.md end-to-end as if loading them cold
