Restore to develop the files where the rescoping added noise without
helping a reader: all of .claude/, the src/ module READMEs that only
described their own filters, ARCHITECTURE.md, TELEMETRY.md, quick-start,
configuration and troubleshooting.
Also drop the "Two estimators, one caveat" table from savings-explained.md.
The page already states that rtk gain estimates bytes/4 and ships no
tokenizer; enumerating the test-side estimator was detail no reader needs.
The user-facing surface keeps the rescoping: READMEs in seven languages,
the guide, hooks, and the analytics and usage pages.
