repo: add path.hooks with absolute and relative suffix formatting

External tool integrations and validation systems need a stable way to
identify where the repository hooks are stored. Currently, this involves
relying on `git rev-parse --git-path hooks` or querying `core.hooksPath`
manually.

Introduce `path.hooks.absolute` and `path.hooks.relative` keys to
`git repo info`. This allows tools to discover the active hooks location
natively, ensuring proper resolution regardless of whether Git is using
the standard `.git/hooks` structure or a custom `core.hooksPath` setup.
