chore: bump similar from 2.7.0 to 3.2.0

[dependabot]

Bumps similar from 2.7.0 to 3.2.0.

Changelog

Sourced from similar's changelog.

3.2.0

• Added structured, line-oriented three-way merging through TextMerge, with merge and diff3 conflict output, configurable labels and marker sizes, owned and borrowed inputs, byte output, and whitespace-insensitive comparison.
• Added WhitespaceMode and TextDiffConfig::whitespace_mode for Git-style line comparisons that ignore changes in whitespace (-b) or all whitespace (-w).
• Changed Algorithm::Myers to reduce unmatched/confusing records and use Git-style bounded, non-minimal splits on expensive searches, and added Algorithm::RawMyers for the previous shortest-edit-script behavior without output-changing heuristics.
• Improved heuristics and performance for most algorithms other than LCS.
• Improved large-input performance by avoiding quadratic Histogram scans.

3.1.2

• Fixed Algorithm::Lcs deadline fallback emitting edits twice, which produced out-of-bounds DiffOp ranges and panics when consuming timed-out diffs. #97
• Fixed Algorithm::Lcs reporting identical subranges with zero-based indices instead of preserving the supplied range offsets. #98
• Fixed Algorithm::Lcs and Algorithm::Hunt emitting zero-length delete operations when both inputs are empty. #99

3.1.1

• Fixed DiffOp cursor positions when compacting adjacent inserts/deletes and in Algorithm::Histogram full-replacement output, ensuring operations form contiguous ranges. #95
• Renamed sample diff input files to a lexicographic caseNN.01.before_* / caseNN.02.after_* scheme.

3.1.0

• Added capture_diff_slices_by_key and capture_diff_slices_by_key_deadline as convenience helpers for diffing slices by derived keys.
• Fixed Compact emitting inconsistent DiffOp cursor positions after compaction, which could leave Delete/Insert operations with stale new_index/old_index values.
• Added explicit lifetime capture (+ use<...>) on iterator-returning APIs to improve compatibility with Rust 2024 lifetime capture behavior. #93

3.0.0

• Added a Git-style Histogram diff implementation exposed as Algorithm::Histogram, including deadline-aware Myers fallback and comprehensive regression/behavior tests.
• Raised MSRV to Rust 1.85 and moved the crate to Rust 2024 edition.
• Added a Hunt-style diff implementation exposed as Algorithm::Hunt.
• Added configurable inline refinement via InlineChangeOptions and

[prql-bot]

Mechanical bump, and similar is a [dev-dependencies] entry of prqlc only — nothing shipped changes.

The one thing worth checking here is that similar 3.0 changed the default Algorithm::Myers to use Git-style bounded, non-minimal splits, and the crate's only direct consumer in this repo is the TextDiff::from_lines(…).unified_diff() call in mod compileall in prqlc/prqlc/tests/integration/queries.rs, whose output goes straight into assert_snapshot!. A heuristic change there would have rewritten those snapshots. It didn't: cargo test -p prqlc --test integration compileall on the merge commit passes 31/31 with no snapshot drift.

Two smaller notes, neither blocking:

• similar 3.x raises its MSRV to 1.85, which exactly meets the workspace rust-version = "1.85.0" — no headroom left. Note that test-msrv and test-deps-min-versions are both gated on needs.rules.outputs.nightly == 'true', so neither runs on this PR; the floor is confirmed by reading, not by CI here.
• Cargo.lock now carries two similar versions, since insta and similar-asserts both pin 2.7.0. #6260 (similar-asserts 1.7.0 → 2.0.0) won't collapse that either, because insta holds 2.x independently. Dev-tree only.

check-ok-to-merge is currently red, but its run (33418584231) has conclusion cancelled — the usual Dependabot-batch concurrency cascade, where a cancelled contributor makes the if: always() gate resolve to FAILURE. The surviving run 33418596908 is still QUEUED and will re-register it. Unverified at approval time: check-ok-to-merge, rules, lint-megalinter, and everything downstream of rules including test-rust.
