Simplify the Enable Abilities API setting description

The previous description packed three sentences and an internal URL into
a single line, making the Stream settings UI visually dense and forcing
users to scan past technical details to find the primary action. Trim to
one sentence that surfaces what enabling does, treats MCP as a
parenthetical secondary fact, and keeps the WP version requirement.

Title is unchanged (still "Enable Abilities API and MCP").
