refactor(design): typed slop catalog in lib/; AI_SLOP_BLACKLIST derived

lib/design-catalog.ts is the single source of truth for gstack's design
anti-pattern vocabulary: the 11 legacy blacklist lines (verbatim, flagged
`legacyBlacklist`), every one of impeccable's 61 registry ids with gstack
prose, tier, impact, confidence, grep heuristic, and /impeccable handoff,
plus the gstack-only tells the LLM pass judges (hero metrics, identical
cards, glassmorphism, missing states, unthemed browser surfaces, ...).

`impeccableId` is set only when the id exists in the registry fixture, and
`renderCatalog({style:'ids'})` brackets an id only then, so rendered prose
never shows an id the detector cannot emit. Role-scoped font lists
(OVERUSED_FONTS_DISPLAY, BANNED_FONTS, FONTS_BODY_UI_OK, FONTS_MONO_OK,
FONTS_VERIFIED_FREE) live beside the entries.

scripts/resolvers/constants.ts now derives AI_SLOP_BLACKLIST from the
catalog. Generated output is byte-identical (bun run gen:skill-docs is a
zero diff). Pure module: no I/O, no scripts/ imports, loading prints
nothing, so bin/ can import it at runtime on every host.

 /**
  * gstack's AI slop anti-patterns — shared between DESIGN_METHODOLOGY and DESIGN_HARD_RULES.
  *
- * Overused fonts worth calling out in templates (not a pattern to blacklist, but a
- * convergence risk): Inter, Roboto, Arial, Helvetica, Open Sans, Lato, Montserrat,
- * Poppins, and increasingly Space Grotesk. Every AI design tool picks one of these.
- * Design prompts should bias toward less-common display faces.
+ * Derived from the typed catalog in lib/design-catalog.ts: the 11 entries flagged
+ * `legacyBlacklist`, prose verbatim, in catalog order. Overused fonts live there
+ * too (OVERUSED_FONTS_DISPLAY), role-scoped: banned as the display voice, several
+ * still fine as body/UI on an Operate or Read surface.
