docs(wiki): align wiki structure with Aetoskia AGENTS.md guidelines

- Renamed `02_architecture.md` to `02_components.md` to match the standard component page naming convention.
- Updated `docs/mkdocs.wiki.yml` to reflect renamed pages and fix navigation label acronym casing (GSDFC, MCP, MkDocs).
- Updated `index.md` to include the mandatory doc model blockquote, standardize section headers with emojis, and accurately map the `Documentation Structure` table to the navigation menu.
- Standardized all wiki pages (`01_overview.md`, `02_components.md`, `03_conventions.md`, `04_iterative_workflow.md`, and `05_development/*`) by:
  - Adding horizontal rules (`---`) between major sections.
  - Applying emoji-prefixed H2 headings for recognizable section types.
  - Appending `## Related` or `## ➡️ Read Next` footers with standard relative cross-links.
  - Adjusting H1 headers to match guide anatomy (e.g., `# Library Overview` on the overview page).

+# Components
+
+`docforge` is split into four horizontal layers. Everything flows top to
+bottom through the CLI.
+
+---
+
+## 1. Loaders & Models
+
+The `docforge/loaders` package wraps `griffe` to extract modules, functions,
+classes, and Google-style docstring sections. Loaded data is normalized into
+the object model under `docforge/models` (`Project`, `Module`, `DocObject`).
+
+---
+
+## 2. Navigation
+
+`docforge/nav` parses `docforge.nav.yml` specs (`NavSpec`, `Resolver`, and the
+MkDocs nav emitter) and, since the wiki kind, derives wiki navigation from the
+file structure via `build_wiki_nav`.
+
+---
+
+## 3. Renderers
+
+`docforge/renderers` turn model data into artifacts:
+
+- `MkDocsRenderer` → `docs/lib/**` reference markdown
+- `MCPRenderer` → `docs/mcp/**` structured documentation
+
+---
+
+## 4. Servers
+
+`docforge/servers` serves generated artifacts over live protocols:
+
+- `MCPServer` → serves a pre-generated `docs/mcp/**` bundle through MCP
+  resources (`docs://index`, `docs://nav`, `docs://modules/{module}`)
+
+---
+
+## 5. CLI
+
+`docforge/cli` wires it all together:
+
+- `commands.py` — the `build` command and its `--mkdocs` / `--api` / `--wiki`
+  / `--mcp` modes
+- `mkdocs_utils.py` — per-kind config generation (`docs/mkdocs.{lib,api,wiki}.yml`)
+  with navigation re-rooted to each kind's `docs_dir`
+- `api_utils.py` — OpenAPI loading and API docs generation
+
+---
