zooqueen 332335ddb4 datastore rebrand: standalone "ClickHouse" word -> "Datastore" (prose, strings, comments)
The correct, safe broad rebrand: renames "ClickHouse" only as a whole word (boundary on
BOTH sides), so it rewrites display strings/messages/comments but leaves every compound
C++ symbol intact — `ClickHouseDictionarySource`, `getInfoIfClickHouseDictionarySource`,
`mainEntryClickHouseServer`, `ClickHouseRevision`, `ClickHouse_SOURCE_DIR` are untouched
(an earlier one-sided heuristic mangled suffix symbols like `manageClickHouse`; reverted).
1677 occurrences across 482 files. Compile-safe (string/comment content; symbols preserved).

Still NOT renamed (would be a build-coupled symbol rename, needs build-host iteration): the
199 compound identifiers containing ClickHouse, the `DB::` namespace, the `clickhouse_*`
CMake targets/macros, the lowercase `clickhouse` SQL dictionary-source keyword. Needs build
verification.
