v0.6.3

MCP domain failures now remain readable in clients that validate structured outputs against success schemas. Errors preserve their code, message, and details as JSON text with isError: true; successful results still include typed structuredContent.

Claim tool schemas explain kind:name resources, and retrieval descriptions call out full-record expansion before consequential use. Pair with Agent Memory plugin 0.1.1.

Validation: 132 application tests, strict typing and formatting, baseline guidance verification, native standalone binary verification, and fresh Codex, Claude, Grok, and Cursor coding trials. Each host retrieved the full relevant memory, claimed before editing, released its claim, and passed the unchanged scheduler tests.
