Max-effort Claude agents + Windows terminal refocus

BridgeSpace 3.1.13 starts Claude agents at maximum reasoning effort by default, and fixes a Windows issue where the active terminal lost keyboard focus after you Alt-Tabbed back into the app.

• Claude agents reason at max effort. Claude now starts with --effort max by default, so agents you spawn from the swarm or the new-workspace wizard reason at full strength without extra flags.
• Terminal refocus after Alt-Tab on Windows. Switching away from BridgeSpace and back now returns the cursor to the active terminal automatically, instead of making you click into the pane first.
