feat: rule tree refactor, anti-slop blocks, framework content, regist…

[joxyle-jhon]

…ry fix

• core/types.ts: add RuleBlock, BlockInclusion, ResolvedBlock, ResolvedRuleTree
• core/resolver.ts: 4-step pipeline — expand ancestors, deduplicate by canonical key (pack priority), build parent-child tree, topological sort
• core/registry.ts: add getAllBlocks() + readBlock(block); fix double-blocks/ path bug that caused all block reads to return empty string
• core/generator.ts: wire resolver pipeline; composeBlocks takes ResolvedRuleTree
• cli/src/types.ts, resolver.ts, registry.ts, generator.ts: mirror all above changes for the Node.js CLI context

Pack configs — migrate string[] blocks to typed RuleBlock[]:

• packs/frontend/pack.config.ts: all blocks typed with id/tags/inclusion
• packs/backend/pack.config.ts: all blocks typed
• packs/fullstack/pack.config.ts: full union of frontend+backend blocks via canonical cross-pack id references (no content duplication); all 11 framework options; all optional blocks from both packs

Framework content — replace stub bullet lists with real rule content:

• packs/frontend/blocks/frameworks/nextjs.md: folder structure, RSC vs CC, Server Actions, data fetching, caching, Route Handlers
• packs/frontend/blocks/frameworks/nuxt.md: useFetch/useAsyncData, Nitro routes, useState vs Pinia, NuxtImg/NuxtLink, middleware
• packs/frontend/blocks/frameworks/sveltekit.md: server vs universal load, form actions + use:enhance, Svelte 5 runes, hooks, route protection
• packs/frontend/blocks/frameworks/angular.md: standalone components, OnPush, signals, RxJS bridge, lazy routes, @defer, NgOptimizedImage
• packs/frontend/blocks/frameworks/vanilla.md: new file — DOM helpers, class component pattern, store, event delegation, Web Components

New blocks:

• packs/frontend/blocks/anti-slop.md: what slop looks like, mandatory checks, spacing/typography/color/component discipline
• packs/frontend/blocks/anti-slop-tooling.md: child of anti-slop — GSAP, Motion.dev, Rive, Lenis, shadcn/ui, Radix UI, Magic UI, Aceternity, Smooth UI, Raylight, Unlumen, Tasteskill.dev, Three.js/R3F; each entry has problem/when-to-reach/when-to-skip/minimal-usage/do-not structure
• cli/src/resolver.ts: new file (mirrors core/resolver.ts, Node-compatible)

UI fix:

• src/components/Generator.tsx: fix optional blocks panel — was reading deprecated pack.optionalBlocks (always undefined); now reads pack.blocks.filter(b => b.inclusion === 'optional') correctly

AGY skill structure:

• .agent/skills/frontend-rules/SKILL.md: moved to AGY-compliant path with required YAML frontmatter

Tests:

• cli/tests/cli.test.ts: 10 new regression tests — Jaccard similarity checks (flags if two framework outputs share >75% word tokens) + keyword presence tests per framework
