[prql-bot]

This bump can't go green without raising the workspace MSRV, so it needs a maintainer decision rather than a merge.

test-msrv fails: cargo msrv verify reports the source is incompatible with the 1.81.0 MSRV declared in Cargo.toml (rust-version = "1.81.0"). The cause is the transitive fallout of the mdbook bump, not the mdbook crates themselves:

• mdbook-core 0.5.3 now requires toml ^1.1.2 (0.5.2 required toml ^0.9.8).
• toml 1.1.2 requires toml_datetime ^1.1.1 and indexmap ^2.13.
• toml_datetime 1.1.1, indexmap 2.14.0, and hashbrown 0.17.1 all declare rust-version = 1.85.

Because the whole repo shares one Cargo.lock, these versions resolve for every workspace member — including prqlc — even though mdbook-core/mdbook-preprocessor are only used by the web/book crate (mdbook-prql). So prqlc's effective toolchain floor jumps from 1.81 to 1.85.

There's no MSRV-compatible pin available while keeping mdbook-core 0.5.3: toml 1.1.2 mandates toml_datetime ^1.1.1, and every 1.1.x of toml_datetime requires 1.85.

Two paths, both maintainer calls:

1. Raise the workspace MSRV to 1.85 in Cargo.toml (rust-version), accepting it for all prqlc consumers — then this PR can merge.
2. Hold mdbook-core/mdbook-preprocessor back until the MSRV is raised independently (e.g. add a Dependabot ignore for the major-version jump driven by toml 1.x), and close this PR.

Not approving, and not pushing a fix, since the MSRV bump is a policy choice affecting downstream prqlc users rather than a mechanical lockfile change.
