Add the inspiration intake→corpus→graduate system (v0.5.0)

[kurenn]

What & why

The skill already reads a shared reference's DNA per build — then forgets it. This makes inspiration an ongoing practice that compounds: an intake → corpus → graduate loop, so each build is smarter than the last.

Seeded from a deep browser intake of 10 premium design sites (the Jakub Antalik showcase set — beam/metal/orbs, plus aicss, canvasui, beautiful-ui, originkit, agentation, transitions.dev, landingfolio).

The loop

• reference/inspiration.md (new) — a living, dated/sourced/tagged corpus + a graduation ledger. On-demand, so the always-loaded router is untouched.
• /prototype intake <url…> (new subcommand) — browse a site in full, distill its DNA, append a corpus entry. Privacy-guarded (only the given URLs).
• Graduation rules — proven moves promote from the corpus into the menus the skill always reads.

What graduated from the first ten

• reference/ai-native-ui.md (new) — the AI-native UI genre: a named thinking-state taxonomy (not one spinner), streaming text, tool-call states, approval cards, task rows — all zero-dep, wired to the existing loading engine.
• build.md — 3 page archetypes (single-artifact showcase · live component catalog · documentation-as-landing) + the playground pattern + legitimacy tells.
• color-palettes.md — a dev-tool near-black ground, reconciled against the blue-on-black reflex it already bans (the line: no glow, no guessable accent).
• type-pairings.md — a dev-tool/AI-native register that explains when the reflex faces (Inter/Geist) are earned — the real signature being mono-for-labels.
• microinteractions.md — number pop-in, spinner→check morph, dissolve-on-remove, card-stack fan (all motion-/reduced-motion-gated).
• ui.js — a stream fakeLatency kind for streaming text.

Guardrails

• SKILL.md stays at 2598/2600 — /prototype intake made reachable by trimming the description; router otherwise untouched.
• Passed an adversarial Fable review; all 12 findings fixed before this PR (unreachable subcommand, a blue-accent loophole in the near-black palette, a fabricated .proto-table class, fakeLatency('stream') made real, reflex-reject reconciliation, missing a11y gate, dangling ledger pointers, contrast count).
• All scaffold JS syntax-checks pass; all cross-references resolve; markdown tables well-formed.
