Asset detail page with notes/ideation (v0.3.25)

[SylonZero]

What

A dedicated /assets/[id] route where an asset's full story comes together — previously assets existed only as cards + an edit sheet inside the Product page.

• Header: type, health, tags, repo/docs links, owner avatars; summary cards for debt score (manual vs derived breakdown), open work items, plan count.
• Description + Notes & Ideation: click-to-edit cards backed by a new assets.notes column (migration 0012, both dialects; postgres hand-written per convention). Notes are markdown-canonical — same dialect the MCP server reads/writes — rendered with react-markdown, ready for the TipTap plan.
• Tabs: Work Items, Tech Debt (with score-derivation note), Code Plans (surfacing per-plan join notes, branch, PR status — captured but barely shown before), Dependencies in both directions with each neighbor's owners and health.
• Inbound links: product-page cards navigate here (edit moved to a pencil button), plus Work Items table asset cells, Tech Debt Register group headers, and My Work "Assets I Own" rows.
• Data layer: getAssetDetail returns the whole context in one call with the same product-access guard as getCodePlan; updateAssetContentAction is access-checked.
• MCP: notes on update_asset, new get_asset tool.

Verification (drove the running app, sqlite)

• Rendered the page for a demo asset: header, summary cards, all four tabs. Saved markdown notes (headings/bold/table) through the real server-action surface — persisted and rendered.
• Probes: cross-org page view → 404; cross-org content write → rejected ("Asset not found or not accessible"); bogus asset id → 404; work-items/my-work links verified with a temp fixture (removed after).
• 167/167 vitest; tsc clean apart from pre-existing errors.
