gix v0.88.0

Bug Fixes (BREAKING)

• preserve causes across fallible conversions

  Rubber stamp, looked at diff. This is a cleanup commit. There is going to be considerable cleanup done later as well.

  Parsers and adapters discarded encoding, integer, date, signature, and object-access failures when replacing them with context. Preserve their concrete causes so classification and downcasting keep working after conversion to gix::Error or an I/O error.

  Return Exn from fallible path, command-line, gitdir, and pack-entry conversions where necessary, and adapt their consumers in the same change. Packed-ref and reflog errors retain their parser sources and input details; reflog recovery reports the actual recovery failure. Loose-object verification now propagates lookup and enumeration failures instead of treating every lookup error as retryable or silently skipping failed enumeration.

  Remove unnecessary UTF-8 conversions for ASCII suffixes and check span bounds before narrowing. Parsers that only return () explicitly destructure it. No production map_err() closure still discards a wildcard-bound error. Also preserve causes in formatting-only CLI and commit-graph adapters, where stringification previously lost checksum corruption classifications.

• locate vi/vim in Git's core directory on Windows; change Repository::editor() -> Option<gix_command::Prepare>

  On Windows, Git's bundled vi may not be available through PATH. Resolve the default editor in Git's core directory first and retain the bare command as fallback.

New Features (BREAKING)

• return the local branches actually deleted

  Callers that needed to know whether branch deletion removed anything had to look up each reference separately. That duplicated reference reads and could report stale existence information by the time deletion took its locks.

  Return sorted, deduplicated full names from the committed reference edits whose previous values were observed under lock. Missing branches are excluded while their stale local configuration is still removed. Expose the same list as deleted in delete::Error::Cleanup so callers can recover it when only configuration cleanup fails; retain references as the full requested batch.

  The success value changes from () to Vec<FullName>, and Cleanup gains
