0.2.0

Added

• Markdown skill system. Notes in <Koda folder>/Skills/ steer Koda's behaviour.
  Each carries a required description and an optional enabled flag in its frontmatter;
  all active skills go into the system prompt when a conversation starts.
• write_skill tool — Koda can author its own skills. Path and frontmatter are built by
  the plugin, not by the model, and the write always asks for approval, even inside the
  Koda folder where every other write is free: a skill changes what the tool does in future
  conversations, so location alone is not enough to grant it.
• The confirmation modal now states in plain language what will change from now on, above
  the unchanged full preview.
• A line at the top of the conversation names the skills currently in effect, plus notices
  when the budget was exceeded or a file was skipped for lacking a description.
• Skill budget setting (default 6000 characters) bounding how much skill text enters the
  system prompt; anything beyond it is listed by description only.

Fixed

• Answers in the sidebar can be selected and copied — Obsidian does not make text in view
  containers selectable on its own.
