Unhelpful error from failure to load analyzer plugin

[parlough]

CI for the Jaspr repository has been inconsistently experiencing a failure due to being unable to load the compiled analyzer_plugin AOT snapshot when running dart analyze. The error is understandable, but there's no actionable suggestion for me on how this state could have occurred.

It's perhaps not a bug in the plugin handling, but it'd be nice if there's more guidance for users that encounter this state.

Versions:

• Dart SDK 3.9.0-3.9.2
• analyzer 7.6.0
• analyzer_plugin 0.13.4
• custom_lint 0.8.0

Error (from https://github.com/schultek/jaspr/actions/runs/17307786694/job/49135028687?pr=531):

File truncated before or at offset 0x0.
