okf 0.4.1

• Use Ack schemas for graph-query parsing and generated, typed MCP arguments. Each input schema owns runtime constraints and the advertised JSON Schema. Partial updates retain omitted fields, and OKF Spec findings and tolerant metadata behavior remain unchanged. Concept IDs stay encoded as strings, and invalid IDs and graph-query fields are reported with their specific paths and validation reasons.
• Generate equality, hashing, copyWith, diagnostic strings, and JSON adapters for index entries, log entries, and legacy citation values with Ack. Use the generated copies when normalizing writable index and log entries, and verify all generated model parts in CI. Const constructors, tolerant parsing, Markdown output, and optional v0.1 citation compatibility are preserved; concept IDs, diagnostics, and documents retain their existing validated constructors and custom formatting.
• Consolidate internal rule metadata, execution context, and YAML value helpers while preserving the public package exports. Remove redundant construction wrappers and use normal constructors where direct initialization suffices. Align IO, MCP, and rule tests with their source modules and consolidate the index/log contract suites without changing their assertions.
• Classify local graph targets containing raw or percent-encoded C1 control characters as invalid, matching bundle-path validation, instead of unresolved.
• Raise the minimum supported Dart SDK from 3.4 to 3.9 for Ack 1.2.
