docs: overhaul documentation site and fix plugin metadata declarations

Rebuild the docs for the new Chronicle content layout (docs/content/docs)
with every fact verified against the code:

- Add quickstart, architecture, scripting guide, and a write-your-first-
  extractor tutorial
- Add per-plugin reference pages for all 35 extractors, 9 sinks, and
  3 processors, replacing links out to GitHub READMEs
- Rewrite examples with complete, runnable recipes
- Rewrite recipe/source/sink/processor concept pages; document scope,
  version, variable precedence, and directory-run semantics accurately
- Fix wrong facts: kafka sink sends JSON (not protobuf), docker commands
  missing the meteor binary name, missing kubernetes/opsgenie/pagerduty
  extractors, stale counts, and broken links
- Remove aspirational Custom Sink and Serializer sections

Code fixes surfaced by the docs audit:

- Align plugins.Info entities/edges with what extractors actually emit
  (confluence, grafana, github, kubernetes, notion, dbt)
- Fix wrong ports in postgres and couchdb sample configs (3306 -> 5432/5984)
- Fix kafka sink README serialization claim
- Update CLAUDE.md: agent/ renamed to runner/
