NotifyCocoonDeltaExtensions.rs

1//! Post-install/uninstall Cocoon notification.
2//!
3//! `$deltaExtensions` adds or removes the supplied descriptors from
4//! Cocoon's extension registry and indexes `activationEvents`, but it
5//! does **not** fire those events. The workbench emits
6//! `$activateByEvent("*")` exactly once at boot; anything installed
7//! later never sees its startup events re-fired. This helper bursts the
8//! single always-satisfied activation event (`onStartupFinished`) after
9//! delta so a VSIX with that trigger activates without a reload.
10//!
11//! Fire-and-forget: missing Cocoon (`Spawn=false`) or a
12//! transient RPC failure is logged and swallowed.
