Finishes the 0.22 release cycle.

Changes

• Adds # 0.22 heading to CHANGELOG.md to trigger CI release
• Documents the release PR workflow in CLAUDE.md: releases must go through a req/MAJOR.MINOR branch and PR, never a direct push to upstream

Changelog entries included

• Fixed digits going into the text field instead of selecting numbered options in choice menus
• Fixed "Yes, and tell Claude what to do next" option in bash permission prompts
• Fixed session tab showing old project display name after IDE restart
• Fixed model discovery failing when Enter was absorbed as a newline in the prompt
