Update wiki for current OSS state (living wiki, MCP capability registry, clustering)
Substantive rewrite of all 15 existing pages plus a new Living Wiki
page. The seed-quality content from the initial wiki commit is
replaced with content grounded in the current codebase — config keys,
env vars, MCP tool counts, sink statuses, language list — read from
the actual implementation rather than stated abstractly.
Key corrections vs the seed: 10 indexed languages (was 7), 23 MCP
tools (was unspecified), MCP off by default, Anthropic as default
LLM provider, server-side QA off by default. The Living Wiki page is
new and honest about which sinks are wired (Confluence + Notion +
git_repo) versus stubbed (the 6 static-site / wiki kinds).
Architecture page documents the internal package layout including
the new internal/livingwiki/ subpackages (assembly, ast, coldstart,
credentials, governance, manifest, markdown, metrics, orchestrator,
scheduler, sinks, webhook). Configuration page is now a definitive
env-var reference grouped by component.
