0.11.0

Big News!!! This release introduces a new UX where Codex is no longer fullscreen / manages its own scrollback, but "appends to the end" and uses the terminal's native scrolling.

This fixes some longstanding pain points:

• https://github.com/openai/codex/issues/1247 copy/paste works now
• https://github.com/openai/codex/issues/1502 use the terminal's native scrolling

But wait, there's more!

• https://github.com/openai/codex/pull/1527 adds support for the /compact command
• https://github.com/openai/codex/pull/1726 introduces an experimental planning tool
• https://github.com/openai/codex/pull/1705 security fix to ensure apply_patch is run through the sandbox for the session
• https://github.com/openai/codex/pull/1764 CLI now checks for new versions and lets you know if you are out of date
