What: Removed dead code for custom notification commands that was never actually implemented.
Details: The customNotifyCommand configuration option was introduced in v0.2.115 but never functioned—it always contained an early return; statement preventing execution. Users who set this option never received custom notifications as it was silently ignored.
User impact: Zero. The feature never worked, so removing it doesn't change behavior.
Evidence: Stub function pb6() at line 406840 present in v2.0.5, removed completely in v2.0.8 (notification function H01() at line 397504 no longer checks for customNotifyCommand)
