What changed

Follow-up to #25 that hardens native OpenRPC support.

• Serialize OpenRPC integer, number, boolean, array, and object parameters according to their documented schemas, including formatted integer types such as integer:int64.
• Support paramStructure: "by-position" by sending positional parameter arrays in document order. Named and either methods continue to send parameter objects.
• Reject invalid scalar values before making a request and reject skipped positional parameters followed by later flags.
• Reject duplicate OpenRPC method names so one CLI command cannot silently shadow another.
• Add rpc:<method> semantics for profile include/exclude filters.
• Use a parameter summary as CLI help text when its description is absent.
• Document the new behavior in the README and both skill guides.

Verification

• npx jest tests/openrpc-to-commands.test.ts tests/openrpc-cli.test.ts --runInBand
• npm test -- --runInBand - 127 passed, 26 expected fixture-dependent skips
• npm run build

Notes

OpenRPC requires unique method names. The follow-up therefore fails fast on duplicate names instead of generating ambiguous commands.
