cleanup(config): move globset to paths configuration - #1536
Conversation
This provides a unified place for the paths globset to be held, from the previous approach of having `Bpf` and `HostScanner` build and hold their own, reducing code duplication and ensuring consistency between the two components a bit better. The new approach requires `Bpf` to take a read lock on the paths configuration for each event it processes, this should be fine since updating the paths value would be the case that might cause contention and it should not be done very often during regular operation.

Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to Malformed path configuration can terminate the application during startup instead of producing a normal configuration error.

- Around line 978-981: Make FactCli::into_config fallible and replace the
expect-based paths conversion with a transposed, propagated result so invalid or
non-UTF-8 CLI/FACT_PATHS patterns return a configuration error instead of
panicking. Update FactConfig::build() and any callers to propagate the new
error.
