feat: v0.2.1 — clickable links, per-plugin deps, Tesseract fix

- MessageThread: Markdown links open in browser (↗) or default app (📂)
  for local file paths. Agent instructed to always use Markdown link
  syntax for paths and URLs in responses.
- plugins/loader: auto-install plugin Python deps via uv on first load
- plugins/types: add dependencies[] field to PluginManifest
- lib.rs: pass RAGDOLL_UV env var + strip Tesseract from PATH
- tauri.conf.json: bump version to 0.2.1
