shell: fish functions -> ~/.local/bin executables + bash/zsh ports; manage ~/.agents

- 16 cross-shell utilities converted to sh/bash chezmoi executables:
  ai c2p cp-appid extract_agents fab gdc gh-sonr-org-migrate ghg-clone
  ghn gho git-summary launch_omp_livediff_overlay lc-elir mdcp mdp pj
  (ghg-clone not named ghg: unrelated cargo binary owns that name)
- cwd/history helpers stay per-shell: yy c cd clip-last + ghg/ghn/gho
  cd-wrappers in bash/functions/ and zsh/functions/, loaded by rc files
- fish keeps only shell-state functions; converted ones now hit PATH
- cp-appid ignore gating moved to .local/bin path
- dot_agents/skills: 82 skills materialized from dotstate storage so
  dot_claude skill symlinks resolve on fresh bootstrap; dotstate
  profile/symlinks.json released .agents/skills .bashrc .zshrc

+description: Create component documentation with installation, usage examples, and preview sections. Apply when documenting 8-bit components with proper structure and examples.
+---
+
+## Component Documentation Pattern
+
+Create comprehensive documentation for 8-bit components following the standard structure.
+
+### Component Preview Structure
+
+Wrap component examples in ComponentPreview with realistic data:
+
+```mdx
+<ComponentPreview title="8-bit ComponentName component" name="component-name">
+  <div className="md:min-w-[300px] min-w-[200px] flex flex-col gap-8">
+    <div>
+      <p className="text-sm text-muted-foreground mb-2">
+        Description of first variant
+      </p>
+      <ComponentName prop={value} />
+    </div>
+    <div>
+      <p className="text-sm text-muted-foreground mb-2">
+        Description of second variant
+      </p>
+      <ComponentName prop={value} variant="retro" />
+    </div>
+  </div>
+</ComponentPreview>
+```
+
+### Simple Component Example
+
+For basic components like Button:
+
+```mdx
+<ComponentPreview title="8-bit button component" name="button">
+  <Button>Button</Button>
+</ComponentPreview>
+```
+
+### Complex Component Example
+
+For components with multiple sub-components like Sheet:
+
+```mdx
+<ComponentPreview title="8-bit Sheet component" name="sheet">
+  <Sheet>
+    <SheetTrigger asChild>
+      <Button variant="outline">Open</Button>
+    </SheetTrigger>
+    <SheetContent>
+      <SheetHeader>
+        <SheetTitle>Edit profile</SheetTitle>
+        <SheetDescription className="text-xs">
+          Make changes to your profile here.
+        </SheetDescription>
+      </SheetHeader>
+      <div className="p-4 flex flex-col gap-4">
+        <Label>Name</Label>
+        <Input placeholder="Project name" />
+      </div>
+      <SheetFooter className="flex-row-reverse">
+        <SheetClose asChild>
+          <Button size="sm">Save changes</Button>
+        </SheetClose>
+      </SheetFooter>
+    </SheetContent>
+  </Sheet>
+</ComponentPreview>
+```
+
+### Usage Section Pattern
+
+**Single import** (simple components):
+
+```mdx
+```tsx
+import { Button } from "@/components/ui/8bit/button"
+```
+```
+
+**Multiple imports** (complex components):
+
+```mdx
+```tsx
+import {
+  Sheet,
+  SheetContent,
+  SheetDescription,
+  SheetHeader,
+  SheetTitle,
+  SheetTrigger,
+} from "@/components/ui/8bit/sheet"
+```
+```
+
+### Props Documentation
+
+For components with props tables, use tables:
+
+```mdx
+### Props
+
+| Prop | Type | Default | Description |
+|------|------|---------|-------------|
+| variant | `string` | `"default"` | Visual style variant |
+| size | `string` | `"default"` | Size of the button |
+| asChild | `boolean` | `false` | Whether to merge props onto child |
+```
+
+### Variant Examples
+
+Show multiple variants in preview:
+
+```mdx
+<ComponentPreview title="8-bit Health Bar component" name="health-bar">
+  <div className="md:min-w-[300px] min-w-[200px] flex flex-col gap-8">
+    <div>
+      <p className="text-sm text-muted-foreground mb-2">
+        Default health bar
+      </p>
+      <HealthBar value={75} />
+    </div>
+    <div>
+      <p className="text-sm text-muted-foreground mb-2">
+        Retro health bar
+      </p>
+      <HealthBar value={45} variant="retro" />
+    </div>
+  </div>
+</ComponentPreview>
+```
+
+### Copy Command Button
+
+Place before ComponentPreview:
+
+```mdx
+<div className="flex flex-col md:flex-row items-center justify-end gap-2 mb-2">
+  <CopyCommandButton
+    copyCommand="pnpm dlx shadcn@latest add @8bitcn/component-name"
+    command="pnpm dlx shadcn@latest add @8bitcn/component-name"
+  />
+</div>
+```
+
+### Key Principles
+
+1. **Preview first** - Show component before explaining
+2. **Multiple variants** - Demonstrate different prop combinations
+3. **Realistic data** - Use meaningful values in examples
+4. **Import completeness** - Include all used imports
+5. **Code block labels** - Use ```tsx for TypeScript
+6. **8-bit components** - Import from `@/components/ui/8bit/`
+7. **Consistent spacing** - Use gap-4, p-4, mb-2 patterns
