collector_build
Diagnostic `nanook::cli::collector_build`
Summary
failed to build collector `{0}`
Details
When this fires
The CLI-side wrapper for a collector build failure. It surfaces during nanook check, nanook probe, or at nanook run startup when CollectorRegistry::validate (or ::build) rejects a [[collectors]] entry. The name in the message is the name = "..." field on the offending block.
What to check
The inner diagnostic carries the actual reason. For plugin-backed collectors, also confirm the dylib is on [plugins].dirs and the manifest entry points at the right pkg.
