[PATCH v3 0/8] repo_config_values: migrate more globals

[Olamide Caleb Bello <belkid98@gmail.com>]

This series continues the effort to remove repository-dependent global
configuration state by moving several core.* configuration variables
into struct `repo_config_values`.

This ensures configuration values are tied to the repository from which
they were read, avoiding cross-repository state leakage in processes
handling multiple repositories, while preserving existing behavior.

All affected configuration values are eagerly parsed. Storing them in
repo_config_values preserves current semantics and avoids introducing
lazy parsing into runtime code paths.

This v3 addresses review feedback by explicitly clarifying the reason
these values belong in repo_config_values (eager parsing) and improving
commit message clarity.
