Boolean property schemas inferred from any make some MCP clients reject the entire tools/list response. Keep the existing Go types and JSON payloads, but provide explicit output schemas for get_task_stats, get_task, and resolve_task.

• Describe dynamic values with object-form anyOf branches covering all JSON types, including null. This preserves protocol-specific statistics, restored snapshots, and extension-defined metadata without imposing download-input restrictions on outputs.
• Cover nested request/option extra fields, including requests inside resource files, as well as get_task_stats.stats.
• Allow null request labels, matching how nil maps serialize.

Validation:

• go test ./pkg/mcpserver ./pkg/rest passes, including actual Streamable HTTP calls to the affected tools and REST integration tests.
• A regression test checks property schemas in the serialized input/output definitions of every tool. Removing the explicit output-schema bindings reproduces failures at all five affected paths across the three tools.
• Output validation covers HTTP/BT/ED2K statistics, restored HLS snapshots, null values, extension extras, and invalid output envelopes.

Fixes #1625
