Bug Fixes

• stop merge-base walks when one paint side is exhausted
  Tested with gix merge-base and noticed that even with gix merge-base @ @~800
  with first: Sha1(707df3375124b51048233625a7e1c801e8c8a7fd) | others: [Sha1(c9c0543b52d8cfe3a3b15d1e39ab9dbc91be6df4)]
  this branch implementation is noticably faster, roughly 10.2ms vs 61.2ms.

  The merge-base walk kept following unrelated ancestry while any queued
  commit remained non-stale, even after one paint color could no longer
  contribute a merge base. Its termination check also scanned the queue
  on every iteration.

  Adapt Git's side-exhaustion optimization from 02d7ba092d: count
  non-stale queued commits carrying each color and stop when either count
  reaches zero in the topologically ordered region. Candidates contribute
  to both counts so they are processed before termination. Track queue
  membership to handle flag changes and duplicate inputs without counting
  a commit twice.

  Keep the existing stale-only termination for missing, zero, or saturated
  generations, where date ordering can revive an apparently exhausted
  color. Continue removing redundant candidates after the paint walk.

  Use existing fixtures to prove that unrelated ancestry is skipped and
  cover pending candidates, duplicate inputs, graph reuse, and clock skew.
  The skipped-ancestry regression fails before this change.

Changed (BREAKING)

• raise MSRV to Rust 1.88

  The newly published dua-core 3.3 release used by linked-worktree removal
  requires Rust 1.88, so raise every workspace crate and the advertised badge
  together.

  Keep the MSRV checks buildable by selecting the latest sysinfo and rusqlite
  release lines that support Rust 1.88.

Bug Fixes (BREAKING)

• preserve merge-base lookup failures

  rubber stamp, but checked the diff and asked for fixes to use gix_error::TestResult instead,
  which for the sake of simplicity is going to happen in a future commit.

  Merge-base traversal replaced object-store and decoding errors with a static
  message. Missing objects, retryable I/O failures, and custom backend errors
  therefore lost their causes and classifications at the revision boundary.

  Return Exn<Message> and raise graph insertion context around the original
  failure. Remove the forwarding Error alias and Simple type, and adapt the
  porcelain API to return gix::Error.

  The regression reproduces the lost backend cause before the fix and verifies
  its concrete I/O kind, missing-resource classification, and retry policy after
  conversion. All 113 revision tests and the porcelain revision tests pass;
  gix and gix-merge compile with the changed signature.
