Patrick v0.3.0

Added

• A guided prompt builder in your profile: write Patrick's instructions as
  labelled blocks — practice context, do's, don'ts, response style, and more —
  that you can add, reorder, and edit, with Raw and live Preview tabs.
• A richer chat composer: format your messages with markdown, and @-mention your
  pinned sources to point Patrick straight at them.
• Patrick can answer questions about itself — what it can and can't do, and how
  to use the app — from its built-in documentation.
• Light rich-text formatting in the prompt-builder blocks and the task brief —
  bold, italic, lists, and (in the brief) headings, via the usual keyboard
  shortcuts and markdown shortcuts.

Changed

• A task now has a single living Brief — what the matter is, the objective,
  and the running record in one place (replacing the separate brief and notes) —
  which Patrick is given on every chat and can draft, refine, or add to.
• Patrick edits your prompt a section at a time: ask him to draft or refine a
  single block (like your practice context) and accept it without disturbing the
  rest of your instructions.
• Profile and task settings keep the title and save status in view as you
  scroll, and the layout now adapts to the panel's width rather than the window.
• A profile's identity is now a profile name plus an author name, which Patrick
  uses as the author on the tracked changes he makes.
