In the trace for 'hows esphome', the model called get with the canonical handle
'system-container-599a2e3...' as resource_id and no resource_type, and it failed
twice with 'resource_type is required' before recovering with 'get 102'. The user
sees those failed tool calls in the chat.
A canonical handle already encodes the type (unifiedresources/ids.go builds ids
as '<type>-<hash>'), so executeGetResource now infers resource_type from the
handle when it's omitted, via resourceTypeFromCanonicalID (the trailing hex hash
segment is unambiguous since no type word is all-hex). A bare numeric VMID still
requires an explicit type. Test TestResourceTypeFromCanonicalID covers it; full
internal/ai/tools green.
