docs: DTail fork — documentation, agent guide, example configsHEADmaster

Squashed development of the documentation and example configuration:

- AGENTS.md / CLAUDE.md: repository guide describing build/test/benchmark/PGO
  workflows and the single default read/output path (formerly "turbo").
- doc/ and docs/: query-language reference, log formats, auth-key fast reconnect,
  journal source reads, performance analyses (dated point-in-time records kept
  under historical-note disclaimers), and the turbo-vs-normal benchmark report
  with its result CSVs.
- README.md updates; examples/ config + JSON schema aligned with the current
  Output* server tuning fields (the removed TurboBoost* keys dropped).
