Fix #7224 docs

[Copilot]

Pull request overview

Updates INPUT-parameter documentation to address Issue #7224’s documentation gaps around out_chg, including the out_chg = -1 behavior and more explicit output file naming.

Changes:

• Expanded out_chg parameter description to document cube output filenames, Meta‑GGA tau outputs, and the -1 “disable restart dump” mode.
• Aligned gint_precision availability text by removing the “on CPU” restriction in the YAML docs.
• Refreshed docs/parameters.yaml entries corresponding to the updated parameter metadata.
