Proqi v0.2.0

Proqi 0.2.0

Proqi 0.2.0 makes the board substantially faster to organize and safer to
control from agents and scripts.

Highlights

• Select several thoughts with Space, then copy, cut, delete, collapse, or
  submit them as one ordered prompt.
• Duplicate the focused thought or selection with Primary+D.
• Scroll overflowing boards one wrapped line at a time, with reliable bounds
  after expanding, collapsing, editing, or resizing thoughts.
• Rename and mutate active sessions through the versioned JSON CLI while the
  owning Proqi TUI remains open.
• Replace thought content idempotently with typed revision identifiers and
  normal persistent editor undo.
• Keep every submitting thought locked until its delivery result is durably
  journaled.
• Preserve older collapse operations and database histories across the current
  schema migration.

The README demo now includes selection, duplication, and grouped deletion, and
uses the same Meslo font family as the tested Ghostty environment when that
font is available.
