chore: update brainpy_state dependency to version 0.0.3 and enhance R…

[chaoming0625]

Summary by Sourcery

Update the brainpy.state integration and dependency while improving ecosystem and state module documentation.

Enhancements:

• Revise the brainpy.state README to provide a full overview, usage guidance, and support information for the state-based programming interface.
• Update the main README ecosystem section to highlight the brainpy-state package and clarify related project links.

Build:

• Bump the brainpy_state dependency from 0.0.2 to 0.0.3 in pyproject.toml and drop the uv.lock file.

Reviewer's Guide

Updates the brainpy_state dependency to version 0.0.3, refreshes and expands documentation around the state-based API, and cleans up project metadata/lock files to align with the new state module packaging.

File-Level Changes

Change	Details	Files
Expand and modernize documentation for the state-based BrainPy API.	Replaced the minimal brainpy.state README with a full module overview describing purpose, features, documentation, source repo, installation, usage, support channels, and licensing details. Standardized README headings and formatting, including explicit description of state-based programming and its integration with BrainPy.	brainpy/state/README.md
Update top-level project README to reflect the broader ecosystem and highlight the new state package.	Reordered the ecosystem bullet list to emphasize the brain modeling ecosystem first, followed by examples. Added a new bullet describing the brainpy-state repository and its role in modernizing BrainPy simulation with brainstate syntax.	README.md
Bump the brainpy_state package dependency and align dependency management with the new version.	Increased the minimum required version of brainpy_state from 0.0.2 to 0.0.3 in the project dependencies. Removed the uv.lock file, presumably to regenerate or stop tracking a stale/unused lockfile tied to the older dependency set.	pyproject.toml uv.lock

Hey - I've found 2 issues, and left some high level feedback:

• The README ecosystem entry for brainpy-state has a typo in the description (Moderize → Modernize).
• Removing uv.lock from version control changes dependency reproducibility; confirm this aligns with the project's dependency management strategy before dropping it.
• The new license notice in brainpy/state/README.md uses Copyright 2025; consider aligning the year and wording with the main project’s existing license headers for consistency.

**nitpick (typo):** Consider adding "the" before "JAX backend" for smoother grammar.

For example: “Leverage CPU, GPU, and TPU acceleration through the JAX backend.”
