v0.2.2: Copy/save buttons, system context file, max tokens setting

- Add Copy and Save as Note buttons on assistant messages (hover to reveal)
- Save as Note uses Obsidian's configured default new-note folder
- Add System Context File setting: vault note appended to every system prompt
- Add configurable Max. Antwort-Tokens setting (slider 1024–16000, default 8192)
  fixes Monthly Check responses being cut off
- helpText textarea auto-expands with content, collapses to 1 row when empty
