Pin collaborator module exports for Tier-13 migration

This change adds explicit __all__ exports to four internal collaborator modules and pins those symbol lists with a new test (`test_tier_13_all_exports.py`), preventing silent internal import drift during the Tier-12→Tier-13 migration while keeping the public API unchanged.

What is Different

Before

Scattered source updates, isolated context, and manual follow-up across multiple feeds.

Now

Stabilized internal module APIs by declaring and enforcing explicit export lists for collaboration helpers, turning undocumented symbol drift into deterministic test failures instead of runtime import surprises.

Why Track This

Why It Matters

Developers and integrators depending on internal NotebookLM collaborator modules now get deterministic CI failures when expected imports disappear, so hidden breakages from internal refactors are caught during migration and fixed before release packaging rather than discovered in production. The PR enforces this through new __all__ exports and export-set tests, so teams can monitor for two follow-ups: intentional symbol removals that need coordinated test updates, and any downstream packages that still rely on undocumented private symbols outside this contract.

What To Watch Next

  • Watch whether __all__ becomes a repeated pattern.
  • Track follow-up changes around LLMOps.
  • Compare future signals against this evidence trail.
  • Re-check risk flags: private_symbol_removal_without_test_update, downstream_private_imports_relying_on_undocumented_symbols.

teng-lin/notebooklm-py PR #860: docs(core): Tier 12→13 migration doc + __all__ on collaborators (Tier 13 PR 13.9b)

Introduced __all__ definitions for `_authed_transport`, `_rpc_executor`, `_conversation_cache`, and `_cookie_persistence`, then added tests to fail CI when those exported symbol sets drift.
