[Env] Reduce the size of default deps to speed up the installation.

[HYLcool]

As the title says. Move 15 default deps to other optional sets and import them with LazyLoader.

Tested on mac based on the pip source from aliyun with python 3.12, uv, and --no-cache:

	Installing time	Num. of installed packages	site-packages size
Before	~1min45s	155	~950MB
After	~25s	88	~350MB

• regression test

Code Review

This pull request implements a comprehensive lazy loading strategy to optimize startup performance and manage optional dependencies. It introduces a post_import hook in the LazyLoader utility, moves heavy libraries like matplotlib, spacy, librosa, and av to optional dependency groups in pyproject.toml, and replaces direct imports with lazy alternatives across the codebase. Additionally, it refactors Ray-based deduplicators to delay actor registration, fixes regex string literals, and disables the resource monitor by default. Feedback recommends moving LazyLoader class imports to the module level for better PEP 8 compliance and consistency.
