// Package server provides the 9P namespace and process state for toolsrv.
//
// The namespace is declared using virtfs and exposes tool execution,
// process management, and bypass request handling.
//
// # Namespace Structure
//
//	/ctl           - control commands (load, unload, clear)
//	/tools         - tool listing (rdwr: write agent ID, read JSON)
//	/all           - all available tools on disk
//	/info          - host info (platform, arch)
//	/bypass/       - bypass request handling
//	/proc/         - process management
//	/proc/new      - execute tool (blocking rdwr)
//	/proc/new.bg   - execute in background (returns PID)
//	/proc/{pid}/   - per-process files (out, wait, stat, ctl)
//
// # Process Execution
//
// Tools are executed via /proc/new (foreground) or /proc/new.bg (background).
// The request includes token, tool name, and arguments. Foreground calls
// block until completion; background calls return immediately with a PID.
//
// # Path Locking
//
// Write-scope tools acquire path-based locks to prevent concurrent writes
// to the same file. Global-scope tools acquire a global lock that serializes
// with everything. Read-scope tools never lock.
