Function lintWiki

lintWiki(vault: Vault, args: LintWikiArgs): Promise<LintWikiResult>
Karpathy-style LLM-Wiki lint — single-call audit of orphans, broken links, stubs, stale notes, and concept candidates.

Implements the "lint" workflow from Karpathy's LLM-Wiki gist (which named ingest/query/lint as the three primitives). Returns five finding buckets, each capped to max_per_bucket for bounded responses. Findings are shaped so the agent can act on them via existing tools (validateNoteProposal → createNote / appendToNote / renameNote).

Concept candidates use a capitalised-phrase heuristic: 1-3 CapitalCase tokens that appear in ≥ concept_min_mentions notes but don't have a page of their own. Stop-words ("The", "This", etc.) at phrase start are dropped.
Parameters
- vault: Vault
  The vault.
- args: LintWikiArgs
  LintWikiArgs. All optional with documented defaults.
Returns Promise<LintWikiResult>
A LintWikiResult with summary counts + per-bucket findings.
Throws
If folder resolves outside the vault.
Example
```
const lint = await lintWiki(vault, {
  folder: "Wiki",
  stub_word_threshold: 50,
  stale_days: 180
});
console.log(`Orphans: ${lint.summary.orphans}, Stubs: ${lint.summary.stubs}`);
for (const f of lint.findings.broken_links) console.log(f.message);
```
