refactor: track imdb retry queue persistence

[Teagan42]

What

• wrap the IMDb retry queue in a tracked asyncio queue that keeps a deque-based snapshot for persistence
• update the retry queue load/process/persist helpers and CLI setup to operate on the tracked structure
• extend the loader retry unit tests to verify queued IDs remain after persisting and loading, and bump the project version

Why

• accessing queue._queue relied on asyncio internals that could change; maintaining our own serialized view keeps persistence safe across Python versions

Affects

• IMDb retry queue management within mcp_plex.loader
• loader retry unit tests

Testing

• uv run ruff check .
• uv run pytest

Documentation

• n/a

Pull Request Overview

This PR refactors the IMDb retry queue to use a tracked queue structure that maintains persistence-safe serialization. Instead of relying on asyncio's internal _queue attribute, it introduces a custom _IMDbRetryQueue class that extends asyncio.Queue and maintains its own deque-based snapshot for safe persistence.

Key changes:

• Introduces _IMDbRetryQueue class that wraps asyncio.Queue with deque-based tracking
• Updates queue loading, processing, and persistence functions to use the new tracked structure
• Adds validation for loaded JSON data format and enhanced test coverage
