[PATCH v2 0/3] migrate encoding settings and bubble up repository

Hi everyone,

As part of the ongoing libification effort and my GSoC 2026 proposal, this series migrates commit and log encoding settings into 'struct repo_settings' and bubbles up the 'struct repository *' dependency.

Previously, 'git_commit_encoding' and 'git_log_output_encoding' were global, where core APIs implicitly rely on 'the_repository'. This series resolves this in three steps:

  - Patch 1: Moves encoding configs into 'repo_settings' using lazy
    -loading, safely handling CLI overrides in 'revision.c'.

  - Patch 2: Updates 'commit_tree()' and related APIs in 'commit.c'
    to accept a repository context, passing it down the call chain.

  - Patch 3: Updates 'pretty_print_commit()' and 'pp_commit_easy()'.
    We leverage existing contextual pointers ('diffopt->repo' and 
    'revs->repo') to pass the repository downwards.

To maintain a clean boundary, leaf callers in 'builtin/' and top-level components (e.g., 'bundle.c') fall back to 'the_repository'.

(Though series passes the full test suite and is verified with 'S ANITIZE=address,undefined', I'm quite certain I must have inadvertently left out some parts. Therefore, this patch series is currently more of a self-archival exercise than a final submission.

For example, I might have left out some of the exsiting contextual pointers in patch 2. Will check in the following days.)

Regards,

Yuchen
