fix: remove unreachable absolute path check in CLI run command

[hobostay]

Summary

• Remove dead code in cli.py:345-350 that checks if working_dir is an absolute path but can never be reached

Problem

In the run() command, the block:

if not Path(working_dir).is_absolute():
    console.print(
        f"[red]Working directory must be an absolute path: {working_dir}, it should start with `/`[/red]"
    )
    sys.exit(1)

is unreachable because both code branches above guarantee an absolute path:

• When working_dir is provided: os.path.abspath(working_dir) on line 336 always returns an absolute path
• When working_dir is not provided: os.getcwd() on line 342 always returns an absolute path

This error message could never actually be displayed to the user.

Fix

Removed the unreachable block.

Test plan

• Verify trae run "task" --working-dir ./relative still works (abspath handles it)
• Verify trae run "task" without working-dir still works (uses cwd)
