The terminal notification system was refactored with cleaner abstractions. Notifications now use dedicated handler functions (sendITerm2, sendKitty, sendGhostty, sendBell) instead of inline escape sequences, making the code more maintainable and easier to extend.
Evidence
gd() at line 367233 (new notification dispatcher using FT5), FT5() at line 367243 (notification router with B.sendITerm2(Q), B.sendKitty(...), etc.), HT5() at line 367266 (auto-detection handler)
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
