Ferry 0.9.2

Added

• Native session forks — branch after a completed answer in Claude Code,
  Codex, OpenCode, Pi Agent and Grok Build, then continue in the new native
  session. Forked sessions can be branched again, with a link back to their origin.
• Resume from a selected answer — copy a Ferry Resume command that includes
  only history through the selected completed turn, including its tool results.
  Fork and resume actions appear as icons beside copy and edit.
