Fix CLI when installed via PATH symlink

[Aurora Capital (auroracapital)]

Summary

cli/desktop-act used dirname $0, which breaks when the script is
symlinked into ~/.local/bin. It now follows symlinks to find the real
repo root.

Test plan

• Global install: desktop-act which / status via ~/.local/bin/desktop-act
• CI green

---

Note

Low Risk
Only the bash CLI wrapper changes; no auth, MCP, or desktop automation logic is touched.

Overview
Fixes global desktop-act installs where the script is symlinked into ~/.local/bin (or similar). Previously ROOT came from dirname $0, which pointed at the symlink directory instead of the real repo, so venv Python and desktop_act_cli.py could not be found.

The entrypoint now walks BASH_SOURCE[0] through symlinks (absolute and relative targets) and uses cd -P so ROOT is the repository root next to cli/.

Warning

Review limit reached

@auroracapital, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 18 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
