Rationale for this change
The IPC reader constructors retain reader state before schema initialization. When schema loading fails, they can return without releasing the message reader.
What changes are included in this PR?
Release the reader state on schema errors and recovered panics, and add a message reader that verifies the release call.
Are these changes tested?
go test ./arrow/ipcAre there any user-facing changes?
No API changes. This corrects the reported behavior while preserving the existing ownership and compatibility contracts.
