Decomplects the browser surface. Previously: BrowserTool with three
braided transports (ZAP, CDP bridge, Playwright) plus a CdpTool alias
that was just a name change. Now: three peer tools, one transport
strategy each, env-gated registration.
Tools (each default-on, each disable-able):
- `browser` — high-level action surface, auto-routes transport.
Disable: HANZO_BROWSER_TOOL_DISABLED=1
- `cdp` — raw Chrome DevTools Protocol method dispatch
(`method=`, `params=`). No Playwright fallback.
Disable: HANZO_CDP_TOOL_DISABLED=1
- `playwright` — same action surface as `browser` but pinned to
backend=playwright (no extension / CDP-bridge).
Disable: HANZO_PLAYWRIGHT_TOOL_DISABLED=1
Transport knobs stay orthogonal to tool selection:
- HANZO_ZAP_DISABLED=1 — don't auto-start the in-process ZAP server
- HANZO_CDP_BRIDGE_ENABLED=1 — opt back into the legacy HTTP bridge
- BROWSER_TRANSPORT=zap|http|auto
- BROWSER_BACKEND=firefox|chrome|extension|playwright|auto
Lifecycle (ZAP server + CDP bridge background threads) moved out of
__init__.py into lifecycle.py. __init__.py is now a pure re-export
surface that resolves TOOLS at import time based on env flags.
CdpTool is now a genuine peer of BrowserTool — method-oriented, not
action-oriented — replacing the alias-subclass from 0.5.5.
