Agent SDK debug logs can go through the storage layer

SDK debug logging tags a session id and can write through the storage layer when given one.

What

The SDK debug logger now mints a session id of the form sdk-<uuid> at startup and, when the caller hands it a storage handle, appends through that instead of writing the file directly. With no handle it writes to the same debug file as before. Only runs when DEBUG_CLAUDE_AGENT_SDK is set.

Evidence

{ namespace: "log", sessionId: Fyi, channel: "debug" }

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
