NB - Native Browser Bridge

Declare it in+`bridge.json` (`"uninstall": "nbrowser_uninstall"`) or ab skips the cascade entirely.++WHY nb needs it more than most bridges: we register **HKCU native-messaging hosts** for Chrome AND+Edge (`Software\<vendor>\NativeMessagingHosts\inc.adom.native_browser`), pointing at a path inside+the cache. Delete the cache without cleaning those and every profile with the extension keeps+dialing a binary that no longer exists - the user gets "Native host has exited" forever, with no+breadcrumb pointing at nb. Verified live: both keys existed and resolved to+`C:/Users/john/.adom/native-browser/host-manifest.json`.++What we clean: both HKCU host keys, `~/.adom/bridges/native-browser`, the activity trail, the icon+cache. What we deliberately do NOT touch: **the nbe extension in the user's browser profile**. That+is theirs; it merely stops working, and `uninstalling-the-extension` walks them through removing it+properly. Never rip an extension out from under a user.++⚠️ THE TRAP THAT ALMOST SHIPPED: ab's registry verbs take **`{hive, key}`**, NOT a single joined+`{path:"HKCU\\Software\\..."}`. A joined path is rejected `bad_args` - and because the cascade is+best-effort (a failure still lets ab delete the cache), it would have failed **silently**, leaving+exactly the orphaned registration the cascade exists to prevent. Check any callback verb's real+signature with `adom-bridge commands` before shipping; do not infer it.
