Bundled plugins only shared the host loader when their entry was compiled
JavaScript, so a source checkout captured all 87 bundled packages (copy, hash,
and dependency materialization) on every prepared model runtime publication:
79.5 s of plugin discovery per agent turn, which exceeded the 120 s budget on
a loaded host. Bundled plugins now take the shared host loader regardless of
entry extension, the edited-code warning keys on the canonical export so it
survives loader interop wrappers, and the docs describe source and compiled
bundled identity together.
Discovery for the live embedded-runner case fell from 79.5 s to 12-13 s and the
case from ~100 s to ~25 s on the same host. Editing a bundled plugin's
TypeScript source now needs a Gateway restart, matching compiled bundled code;
installed, external, workspace-path, and standalone plugins keep captured
source reload semantics.
