feat: improve background startup and launcher control

Detach --background launches from terminals with quieter runtime output, make wrapper/plugin overlay start explicit, and allow trailing commas in JSONC configs for safer hot-reload edits. Includes pending Anki/docs/backlog updates in this unreleased batch.

+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+Support configuring tags applied to cards created or updated through SubMiner's AnkiConnect workflow. Default behavior should add the `SubMiner` tag to all mined/updated cards, while allowing users to override or disable automatic tagging via config.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [x] #1 AnkiConnect note creation supports passing tags.
+- [x] #2 Existing-card update flows add configured tags via AnkiConnect after updates.
+- [x] #3 Default config includes `ankiConnect.tags: ["SubMiner"]`.
+- [x] #4 Config parsing validates `ankiConnect.tags` and falls back safely on invalid values.
+- [x] #5 User-facing docs/config examples mention the new tags option and default behavior.
+<!-- AC:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Implemented configurable AnkiConnect tagging across SubMiner card creation and update workflows. Added `ankiConnect.tags` config (default `['SubMiner']`), validation/fallback in config parsing, AnkiConnect client support for `addNote` tags + `addTags`, and integration hooks so created/updated/merged cards receive configured tags. Updated docs and regenerated config examples; config test suite passes.
