Bedrock Claude Opus 4.6 and Sonnet 4.6 models have 200k context
window, not 1M. Removed incorrect overrides that were forcing these
models to 1M. The native Anthropic API models correctly remain at 1M.

When running inside a sandbox (e.g., bubblewrap) that blocks access

undefined. Previously this was treated as "extended-keys is off",
showing a false warning. Now we skip the warning when the tmux server
can't be reached.
Use cmd-based VS Code launcher on win32 in /diff and /files.
Show explicit error details when open fails.
In /diff, surface git difftool failure and troubleshooting hint.
