docs: sync README with source of truth (#3063)

* docs: sync README with source of truth

manifest.json marks cursor agent as disabled:true, but README still showed
9 agents / 54 combinations in the tagline and had a Cursor CLI row in the
matrix table. Updated tagline to 8 agents / 48 combinations and removed
the Cursor CLI row from the matrix.

* fix: correct agent/cloud/combination counts in README tagline

The tagline claimed "8 agents. 6 clouds. 48 working combinations." but
the local cloud should be excluded from the user-facing count (users
don't deploy to their own machine via a cloud provider). With cursor
disabled, the correct counts are 8 agents x 5 non-local clouds = 40
working combinations.
