Pull request overview

Automated subtree sync that pulls in the latest source/taos-community changes, spanning benchmark tooling fixes, catalog teardown hardening, parser/stream logging tweaks, new RocksDB diagnostic utilities, test adjustments, and substantial documentation/release-notes reshaping.

Changes:

• Improve taosBenchmark mixed-query result file handling (per-SQL output file selection and avoiding writing RESET QUERY CACHE responses into result files).
• Harden catalog teardown behavior around timer callbacks and cache-size iteration, plus minor correctness fixes (errno handling, format specifiers, clearer secrets/token examples).
• Add tools/rdb-selftest diagnostic utilities gated behind BUILD_DIAG_TOOLS, and update docs structure/content (roadmap, release notes, integrations).
