Mechanical dev-dependency bump; the diff looks correct to me.

• All six similar_asserts::assert_eq! call sites use the macro API, which 2.0 leaves unchanged — the changelog's breaking items are the Rust 2024 edition, the 1.85 MSRV, and the similar 3.0 upgrade, none of which touch the macro surface.
• MSRV: 2.0.0's new floor of 1.85 exactly matches the workspace rust-version = "1.85.0" and the manually maintained metadata.msrv key in prqlc/prqlc/Cargo.toml, so there is no headroom left; test-msrv is the gate if that reading is wrong.
• The lockfile is coherent: console dedupes onto 0.16.3 (shared with insta) and windows-sys 0.59.0 drops out. similar now appears twice — 2.7.0 for insta and prqlc's own direct dep, 3.2.0 under similar-asserts — and the similar/inline feature moves with similar-asserts onto 3.2.0, which is why the 2.7.0 entry loses its bstr/unicode-segmentation edges. #6261 bumps the direct similar to 3.2.0 but its lockfile leaves insta on 2.7.0, so the two copies persist whichever way the pair lands. [profile.dev.package.similar] matches by name, so opt-level = 3 still applies to both.

CI is unverified: the whole tests matrix is QUEUED behind today's Dependabot batch, including test-rust, test-msrv and test-deps-min-versions, which are the checks that would actually exercise this. The red check-ok-to-merge belongs to run 33418570096, whose own conclusion is cancelled — it is superseded by the queued run 33418576303, not a real failure.
