Summary

• Decouples vide_core services from claude_sdk-specific types — core business logic now depends only on the provider-agnostic agent_sdk interface
• Adds bidirectional type mappers in the claude_sdk bridge layer (toClaude/fromClaude) so provider-specific conversions happen at the boundary
• Fixes 3 type-safety regressions: Object? parameter in createForked, ClaudeAgentClient cast in forkAgent, and raw parameter map access in TUI renderers
• Adds typed tool invocation subclasses (AgentWriteToolInvocation, AgentEditToolInvocation, AgentFileOperationToolInvocation) to agent_sdk with factory dispatch
• Replaces MockClaudeClient with MockAgentClient in all vide_core tests

Changes by package

agent_sdk — New typed tool invocation hierarchy, permission models, createTyped() factory, path dependency

claude_sdk — Reverse mappers (toClaude) for conversation, message, response, permission types. New test suites for round-trip verification

vide_core — All services use AgentClient instead of ClaudeClient. createForked takes AgentConversation? instead of Object?. Removed ClaudeAgentClient import from agent_lifecycle_service. Tests migrated to MockAgentClient

TUI — Renderers use typed invocations (is AgentWriteToolInvocation, etc.) instead of raw parameters['file_path'] map access

Test plan

• dart analyze clean across all 4 packages (agent_sdk, claude_sdk, vide_core, root)
• dart test packages/agent_sdk — 37/37 new typed invocation tests
• dart test packages/claude_sdk — 759/759 (32 new reverse mapper tests)
• dart test packages/vide_core — 504/504 (all tests migrated to MockAgentClient)
• Verified no remaining ClaudeClient/ClaudeConversation references in vide_core/lib
• Verified no remaining raw parameters['...'] access in TUI renderers
