chore(release): 0.0.7

Squash-merge lib-standardisation: adopt repo standards across packaging,
tooling, docs, and CI.

- standardize pyproject.toml (canonical packaging, lint config, extras, GSDFC pydoclint)
- add py.typed marker, modernize type hints and Google-style docstrings
- nest generated docs under docs/lib and docs/mcp; add hand-written wiki
- adopt standard Type A PyPI CI pipeline (tag==version guard + quality gate)
- promote generated CHANGELOG.md; bump version to 0.0.7

+# 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
+
+---
