Highlights:

• Rate limits visibility: You can see when is your limits resetting (#4111) and see your usage when rate limited (#4102)
• You can specify output schema in exec mode using output-schema. (#4079)
• Ripgrep (rg) is now vendored into the npm release (#3660), which should fix issues such as #3842 where the postinstall step of @vscode/ripgrep would sometimes fail when installing codex via npm.
