What's New

Workspace Identity Resolution for MCP Servers

Claude Code doesn't propagate WMUX_WORKSPACE_ID environment variables to MCP child processes, causing agents to be unable to identify which workspace they belong to. This release fixes the core issue:

PID-based identity resolution: PTYManager writes shell PID→workspaceId mappings to ~/.wmux/pid-map/ on PTY creation (both local and daemon modes)
Process tree walking: MCP servers resolve their workspace identity by calling a2a.resolve.identity RPC, then walking the process tree upward via PowerShell to find the matching PTY shell PID
Removed dangerous fallback: The activeWorkspaceId fallback that caused identity confusion when focus changed between workspaces has been removed. All A2A operations now require explicit workspace identity
Clear error messages: When workspace identity cannot be determined, agents receive actionable error messages instead of silently using the wrong workspace

Company Mode Scaffolding

Company/department/team member data model and store
Agent persona generator, cost estimator, message queue
Built-in company templates
Company RPC handlers and worktree management
wmux-a2a MCP server for structured inter-agent communication

A2A Protocol Improvements

a2a.resolve.identity RPC for workspace identity resolution
Background task execution via ClaudeWorker
Improved task routing and workspace matching
