[2/8] Correct compatibility and diagnostic guidance

[JanProvaznik]

Part 2 of 8

Replace incorrect API, warning, ChangeWave, logging, and transport claims with source-backed guidance and focused references. Preserve current-main TerminalLogger instructions.

Depends on #14962. Next: #14964. Full index: #14961.

This PR is based on janprovaznik/context-01-foundations. Files changed shows only this chapter. Review bottom-up; after the preceding chapter lands, retarget this PR to main before merging. Do not merge later chapters into temporary stack-base branches.

Scope and evidence

Guidance is checked against the referenced source/configuration, and this chapter introduces no new broken local references. No product runtime behavior is claimed to have been re-executed by a documentation change.

Agentic-workflow changes remain separate. This stack does not include personal plugin overrides, plugin auto-activation changes, or SDK/feed version changes. The public descriptions use public repository evidence, not internal discussions or proprietary source.
