* add automatic OSC 7 support to bash and zsh
* add new wave OSC 16162 (planck length) to get up-to-date shell
information into blockrtinfo. currently implemented only for zsh. bash
will not support as rich of data as zsh, but we'll be able to do some.
* new rtinfo will be used to provide better context for AI in the
future, and to make sure AI is running safe commands.
* added a small local machine description to tab context (so AI knows
we're running on MacOS, Linux, or Windows)
Massive PR, over 13k LOC updated, 128 commits to implement the first pass at the new Wave AI panel. Two backend adapters (OpenAI and Anthropic), layout changes to support the panel, keyboard shortcuts, and a huge focus/layout change to integrate the panel seamlessly into the UI.
Also fixes some small issues found during the Wave AI journey (zoom fixes, documentation, more scss removal, circular dependency issues, settings, etc)
