Prepare the requested 0.1.1 patch release through Changesets and remove the README Usage section. The release records the skills.sh grouping and automatic refresh changes.

Note

Low Risk
Release metadata and README documentation only; no runtime or security-sensitive code in this diff.

Overview
Prepares bStack 0.1.1 as a patch release via a new Changesets entry that records grouping the skills.sh listing by workflow, refreshing that listing after releases, and simplifying the README.

The README change in this diff drops the Usage section (how to invoke skills with /unslop, $unslop, etc.); the skills table and install instructions stay as-is.

Risk: low. Approved: Cursor Bugbot completed successfully with no findings that need human review, and this is a narrow changeset plus README documentation change. No prior approval from this automation to re-evaluate.
