Bug Fixes

• skip null-ID lookups in worktree filters

  core.autocrlf=input or text=auto can make worktree diff filtering look
  up a null resource ID to inspect indexed line endings. These guaranteed
  misses can trigger repeated pack-directory refreshes until
  #​2853 is merged.

  Treat null IDs as a missing index object before consulting the database.
  Clarify the worktree resource contract and add a regression test covering
  both Git conversion modes and preservation of indexed CRLF content for
  real IDs.

Changed (BREAKING)

• migrate errors to gix-error

  rubberstamp

• 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.

One blocking finding on the version skew this bump introduces between gix and gix-diff. Details inline on Cargo.toml.

[ferrfleet]

Blocking: this bump splits the gix graph in two. gix 0.87 pins gix-diff ^0.67.1, gix-object 0.64.1 and gix-hash 0.26.2; gix-diff 0.68 pulls gix-object 0.65.0 and gix-hash 0.27.0. The lockfile in this PR now carries both trees side by side (gix-diff 0.67.1 + gix-diff 0.68.0, gix-object 0.64.1 + 0.65.0, gix-hash 0.26.2 + 0.27.0).

src/git/diff.rs crosses that boundary in a single call:

• TreeRefIter::from_bytes(...) is gix::objs::TreeRefIter, i.e. gix-object 0.64, but gix_diff::tree() now wants gix-object 0.65's type.
• &repo.objects satisfies gix-object 0.64's Find, not 0.65's.
• hash_kind from repo.object_hash() is gix-hash 0.26's Kind.

Those are distinct types to rustc, so I do not expect this to compile. Test and Build Release Binary were still in progress when I looked, so CI has not confirmed it yet, and automerge is enabled here: the required checks are the only thing holding it.

The fix is not confined to this line, which is why there is no suggestion block. I would drop the direct gix-diff dependency and go through gix's own re-export: gix::diff is ungated in 0.87 and exposes everything src/git/diff.rs uses (gix::diff::tree, gix::diff::tree::Recorder, gix::diff::tree::recorder::Change). That makes this kind of skew structurally impossible and leaves one crate for Renovate to bump instead of two that have to move in lockstep. The alternative is to keep the direct dependency pinned at 0.67 until gix 0.88 moves to gix-object 0.65, and add a Renovate group so the two are always bumped together, but that only defers the same failure to the next release.
