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.

+# Unit suites

+`npm test` runs `node --no-warnings --test tests/*.test.ts` — 43 tests, no test framework installed, nothing
+external. The analyst and Jev are exercised through injected `fetch`, so no key and no network is needed.
+
+Constraints that shape the code, not the tests: modules loaded by bare `node --test` cannot resolve the `@`
+import alias, so test-imported modules import each other by relative `./x.ts` path (which is why
+`allowImportingTsExtensions` is on), and `next/headers` plus `next/navigation` are imported lazily inside
+`lib/auth.ts`.
+
+The digest suite is the one that grew teeth: it now asserts nesting depth beyond the parser default, table names
+taken from `<Object>` children, character-reference decoding, six plan-file encodings, and that a truncated plan's
+error names a reason.
