ec99a97957 feat(phase-9.75g-0): Implement BID-FFI Day 2 - Metadata API and plugin lifecycle
BID-1 Implementation Progress (Day 2 Complete\! 🎉):

Metadata API Implementation:
- Add NyashHostVtable for host function integration
  - Memory allocation/free functions
  - FutureBox wake support
  - Logging capability
- Implement plugin metadata structures
  - NyashPluginInfo: type_id, type_name, methods
  - NyashMethodInfo: method_id, method_name, signature_hash
  - PluginMetadata: Rust-side holder with lifecycle state

Plugin API Definitions:
- Define C FFI function signatures
  - nyash_plugin_abi(): Get ABI version
  - nyash_plugin_init(): Initialize with host vtable
  - nyash_plugin_invoke(): Unified method invocation
  - nyash_plugin_shutdown(): Cleanup resources
- Implement PluginHandle for loaded plugin management
- Add two-call pattern support for dynamic result sizes

Test Coverage: 7/7 
- bid::types::tests (2 tests)
- bid::tlv::tests (2 tests)
- bid::metadata::tests (2 tests)
- bid::plugin_api::tests (1 test)

Everything is Box philosophy progressing with practical FFI design\!
