Current evaluation

Existing instances are reused without validating requested hardware settings; a maintainer asked for elaboration, but the mismatch policy and covered specifications remain unspecified.

Suggested action: needs triage

Reason: Multipass returns an existing instance after warmup without comparing the requested cpus, memory, or disk values, so the behavior described is valid. However, lengau asked for elaboration and received no response, leaving the applicable provider and specifications, mismatch handling, and whether invalid values should only warn or also trigger auto-clean unclear.

Issue body

### What needs to get done When an instance is requested to launch, but one already exists, the hardware specs should be verified. ### Why it needs to get done If an instance already exists, then specs are ignored and the instance is used regardless of its actual hardware specs. This could lead to unexpected behavior.
