phase-2 work (sending webmail, clearing session-bound gates like peopleconnect guided-mode) needs
the operator's own logged-in browser, not a cloud browser. new `pdd.py cdp`:
- finds chrome/chromium/brave/edge (macos/linux/windows), launches it detached on a dedicated debug
profile ($HERMES_HOME/chrome-debug) with --remote-debugging-port, waits for the port, prints the
CDP endpoint (webSocketDebuggerUrl)
- `--check`: report whether a debug browser is already live (never double-launches)
- `--print`: emit the exact command for the operator to run themselves
- doctor, SKILL.md, and methods.md all point at it
- windows-safe detach (start_new_session on posix, DETACHED_PROCESS on windows); stdlib only
tests: standalone 98, PR 96 (+6 cdp); ruff + windows-footguns clean.
