refactor(packaging): align pyproject.toml with PEP 621 (#13)

refactor(packaging): Align pyproject.toml with PEP 621 metadata standard

This commit migrates package metadata from the `[tool.poetry]` section to the standardized `[project]` table as specified by PEP 621.

Key changes:
- Moves core metadata (name, version, description, authors, etc.) to the `[project]` table.
- Updates the `license` definition to correctly reference a custom license file, resolving validation warnings.
- Updates the `requires-python` specifier to be PEP 440 compliant, fixing a `ruff` pre-commit hook error.
- Confirms the package remains buildable with standard PyPA tools (e.g., `build`) for PEP 517/518 compliance.
- Retains Poetry-specific dependency tables (`[tool.poetry.dependencies]`) to ensure full compatibility with Poetry's development workflow.
