fix(il2cpp): preserve loader ownership and ABI field boundaries

Resolve pointer and scalar facts through their shared loader-aware owners before registration search or type rendering. Preserve unresolved names and attributes, read count fields at their declared width, and admit declared zero-fill registration tails without accepting unmapped bytes.

Cover relocation overlap and adjacency, loader-bound fields, ABI padding, nullable names, and CLI/MCP behavior; document format and verification limits.
