[FEATURE] Pass <ide_opened_file> and <ide_selection> to command invocations

Preflight Checklist

Problem Statement

I would like to run a .claude/commands/foo.md command against the currently opened file. I switch focus to the Claude Code pane and type /foo. However, the command is not passed <ide_opened_file> nor <ide_selection> and so does not know my context, does not know which file I am looking at.

Is there a reason commands don't receive <ide_opened_file> nor <ide_selection>?

Proposed Solution

Pass <ide_opened_file> and <ide_selection> to /command invocations.

Alternative Solutions

Currently, I run my commands as @foo instead of /foo.

Priority

Low - Nice to have

Feature Category

Interactive mode (TUI)

Use Case Example

Suppose the command is fix-todos.md which says Address all TODO comments in the currently opened file.. /fix-todos will not work -- lacks <ide_opened_file> -- even though typing those instructions manually into the chat pane will work -- receives <ide_opened_file>.
