Fixes #1561. Adds a CustomToolInput dataclass and CustomTool dispatch branch (mirroring the existing HostedMCPTool precedent), so Workflows exposing any CustomTool subclass — notably SandboxApplyPatchTool, which the default Filesystem capability registers on every SandboxAgent — no longer fail with `ValueError: Unsupported tool type: apply_patch` at Activity input construction. Also round-trips `defer_loading` through `tool_config`, so direct `CustomTool(defer_loading=True)` callers continue to work with `ToolSearchTool()` lazy tool discovery.

basedpyright in CI flagged the inline async stub callable for missing type annotations and unused-parameter warnings. Adds Any/str annotations and underscore-prefixes the params. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
