Feature Request: Allow configuring base branch for 'Commit changes' diff view

[GanapatiNar]

Problem

The "Commit changes" diff view always compares against `main`, regardless of which branch you are currently on.

For users working on long-lived branches (e.g. `env/uat`), this is misleading — it shows a large diff of all changes since `main` rather than actual uncommitted/unstaged changes.

Expected Behavior

Compare the diff against the current branch's remote tracking branch (e.g. `origin/env/uat`) instead of hardcoding `main` as the base.

Alternatively, allow users to configure the base branch in Claude Code settings (e.g. `~/.claude/settings.json`).

Workaround

Use `git diff origin/` in the terminal instead.

Environment

• Claude Code CLI
• Branch: `env/uat`
