feat(ADR-0046): lightweight chrome (DocShell) for the docs routes

[xuyushun441-sys]

Why

The /docs portal and /docs/<name> viewer are app-independent top-level routes, so they rendered as bare full-bleed pages — no header, no breadcrumb, no way back. After the typography fix (#1687) the content looks right, but the page still felt unfinished/floating.

Change

A minimal, shared DocShell sticky header used by both pages:

• a "📖 Documentation" home link → /docs
• a breadcrumb of the current doc (label) on the viewer

No app sidebar — that keeps ADR-0046's stated "no navigation taxonomy in v1" intent. This is just orientation + a way out. The portal's redundant in-body Documentation title is dropped in favour of the header.

Verification (live, browser)

Ran the console against a docs-serving backend and exercised both routes:

• Portal /docs: sticky header + SHOWCASE group listing Documentation Guide / Showcase with machine names.
• Doc /docs/showcase_index: header breadcrumb Documentation / Showcase, then the typography-styled body (h1 30px, spaced paragraphs, chip inline-code, themed links).
• Back-link: clicking "Documentation" in a doc header returns to the portal (which shows the groups).
• No console errors.

Screenshots of both states captured during verification.

Stack

Builds on #1687 (typography). Together: docs now render styled and have basic chrome.
