docs: karpathy-pattern wiki built from the spec, plan, design contract and decisions ledger

kb/ is its own wiki root: 34 pages across 7 categories, index.md catalog, log.md, AGENTS.md schema layer, and raw/ holding copies of README, the spec, the 13-task plan, the design master and the SDD ledger.

Every page cross-references 3 to 6 others and all 107 wikilinks resolve except two [["list"]] artefacts inside JSON snippets in the copied plan.

Kept separate from the repository root on purpose: its generated graph lands in kb/.ua/ instead of overwriting the code graph.

+# Analysis row lifecycle
+
+A row is created before the plan is validated, so every attempt is visible in the rail. Status moves through
+`running` → `done` | `failed` | `partial` | `abandoned`.
+
+`partial` means some stages produced output before the run stopped. `abandoned` means the browser went away
+mid-run. Both surface as pills in the history rail rather than being hidden, and `/app/[id]` renders whatever
+exists with a "this run was interrupted before it finished" note.
+
+`/app/[id]` never redirects a `running` row. An earlier version did, which turned a row orphaned by a crashed
+process into an infinite self-redirect.
