// Tag autocomplete — CodeMirror completion sources.
// Three parallel namespaces, one trigger for each:
//   - tagCompletionSource: booru tag CSVs (configured in tags-dropdown.js),
//     fires on plain word typing.
//   - `@`-prefixed sources for the curated PromptChain tag-builder DB:
//       atTypePickerSource — types list, fires on `@<word-chars>` (no space).
//       <type>ValueSource  — value lookup, fires on `@<type> <query>`.
//       cascadeCompletionSource — internal flow after picking a character
//                                 (auto-pops outfit then pose).
//   - `$`-prefixed: mannequinRegionSource — the 3D Poser's figures that have
//     no $name{} region block in this prompt yet; picking one inserts the
//     block with the cursor inside.
