/**
 * Global pointer to the active REPL bridge handle, so callers outside
 * useReplBridge's React tree (tools, slash commands) can invoke handle methods
 * like subscribePR. Same one-bridge-per-process justification as bridgeDebug.ts
 * — the handle's closure captures the sessionId and getAccessToken that created
 * the session, and re-deriving those independently (BriefTool/upload.ts pattern)
 * risks staging/prod token divergence.
 *
 * Set from useReplBridge.tsx when init completes; cleared on teardown.
