fix(divan): bump proc-macro-crate to parse multiline inline tables

[GuillaumeLagrange]

Bump proc-macro-crate from 3.2.0 to 3.5.0 in the divan compat macros crate so that the bench macro can parse consumer manifests that use multiline inline tables.

The divan::bench macro resolves the (often renamed) codspeed-divan-compat dependency by calling proc_macro_crate::crate_name, which parses the consumer's Cargo.toml with toml_edit. proc-macro-crate 3.2.0 pulled toml_edit 0.22, which parses in strict TOML 1.0 mode and rejects multiline inline tables — a TOML 1.1 feature that Cargo itself accepts. When a manifest contained one (e.g. a long features = [...] list wrapped across lines by a formatter), parsing failed, the rename could not be resolved, and the macro silently fell back to the unrenamed codspeed_divan_compat path, producing:

error[E0433]: cannot find `codspeed_divan_compat` in the crate root

proc-macro-crate 3.5.0 depends on toml_edit 0.25 (+spec-1.1.0), which parses multiline inline tables, so the rename resolves correctly.

This surfaced from a real user report (biome): after a CI formatter rewrapped a dependency in biome_module_graph/Cargo.toml into a multiline inline table, their divan benchmarks stopped compiling. Reproduced the exact E0433 with proc-macro-crate 3.2.0 / toml_edit 0.22 against that manifest shape, and confirmed it compiles cleanly with 3.5.0 / toml_edit 0.25.

The crate's MSRV is raised 1.80 → 1.85 to match the rest of the workspace (proc-macro-crate 3.5.0 requires 1.82, and the parent codspeed-divan-compat lib is already 1.85, so this is not a consumer-facing bump). The CI msrv-check job for divan_compat passes at 1.85.

Closes COD-3022

Greptile Summary

This PR updates the Divan compatibility macro dependency used to resolve renamed crates.

• Bumps proc-macro-crate from 3.2.0 to 3.5.0.
• Updates the lockfile for the newer TOML parser dependency stack.
• Raises the macros crate rust-version from 1.80 to 1.85.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.
