Add shared, typed input-contract and timeout-state recovery guidance. Normalize SDK input failures within the actual MCP wire budget, preserve full diagnostics and protocol metadata, and retain original Evidence when normalized delivery would exceed the budget.
Fixes#5431.
Keep exact wildcard, whitespace and aligned-mask validation in the shared
domain refinement. Advertise descriptive string inputs instead of repeating
regexes, and remove discarded byte/mask array materialization.
Preserve caller spelling and error precedence; cover large public stdio
queries, provider-boundary parsing and connection recovery.
Fixes#5257
