Update .gitignore and fix license format in pyproject.toml

[barnett-yuxiang]

User description

When executing in the current main branch code, the following error message is encountered.

poetry install

The Poetry configuration is invalid:
- project.license must be valid exactly by one definition (0 matches found)

The problem is in your pyproject.toml file with the license configuration. Poetry expects a specific format for the license field, but your current configuration is incorrect.

The error message indicates that your license definition doesn't match any of the expected formats for Poetry. Currently, your license definition is:

license = { name = "Apache 2.0", file = "LICENSE" }

This format works for PEP 621 (standard Python packaging), but Poetry requires a different format.

Fix

Use a simple string

license = "Apache-2.0"

Make sure you're using the standardized SPDX identifier "Apache-2.0" instead of "Apache 2.0" (note the hyphen).
