Implemented brokerd::args: a pure module (no I/O, no clock) that parses tool arguments into a typed ToolArgs and checks the form of paths, hosts and URLs. Four private deny_unknown_fields structs drive parse and canonical_json; path, cwd and url are validated as written and never normalised. All 13 args tests pass and make gate prints gate: ok. Implemented-By: OpenCode session (model recorded in docs/implementer-log.md)
