Motivation

Due to the omission of RUSTUP_TOOLCHAIN, both build_stable.yml and build_msrv.yml were not validating the toolchain version they're supposed to validate as both resolved to rust-toolchain.toml, effectively turning them into near duplicates of build_nightly.yml.

This in combination with an oversight in how builds were executed at all meant that MSRV guarantees were unmet (due to the dependency graph requiring MSRVs higher than 1.85) and uncaught (due to the above omission; without which the build should have failed with a hard error).

This pull request attempts to mitigate these failures.

How Has This Been Tested?

./contrib/git_filter.py --fast-fail develop lint_p3 -- bash -c "python3 ./contrib/lint_all.py"

📝 Walkthrough

Walkthrough

The PR adds shared lint utilities, introduces Cargo formatting and MSRV checks, updates lint parsers, reformats Cargo TOML, configures Taplo, and pins CI commands to explicit Rust toolchains.

Changes

Lint and CI consistency

Layer / File(s) Summary
Shared lint harness
contrib/common.py
Adds workspace roots, shared verb parsing, exit-code handling, and secure changed-file detection.
Cargo formatting and MSRV validation
contrib/lint/lint_cargo.py, .taplo.toml, pyproject.toml, contrib/samples/*/Cargo.toml, pkgs/*/Cargo.toml
Adds Taplo checks and Cargo MSRV validation across workspace roots and target triples. Adds Taplo formatting rules and a platform marker.
Lint command integration
contrib/build_docs.py, contrib/lint_codeql.py, contrib/lint_rust.py, contrib/lint/lint_unconv.py, contrib/lint_all.py
Updates lint entry points to use declare_verbs. Rust linting derives manifests from shared workspace roots.
Explicit CI toolchains
.github/workflows/build_msrv.yml, .github/workflows/build_stable.yml
Pins MSRV commands to 1.85.0, separates dash-pow builds and tests, and pins stable commands to stable.

Merge Risk: 🟡 Moderate · up to c689d

The PR strengthens Rust toolchain and lint validation, but the current changes still prevent documentation deployment and leave the default command selecting a mutating operation. Merge should wait for these issues to be fixed or explicitly accepted by the owners.

In `@contrib/build_docs.py`:
- Line 212: Update the verb mapping and default-selection behavior around
declare_verbs so invoking the command without a verb does not select the
mutating _build operation. Require an explicit build or preview verb, or place a
non-mutating operation first as the default, while preserving the existing
explicit build behavior.

In `@contrib/common.py`:
- Line 103: Update the touched-file filter around the name and repo_root checks
to reject symlinks before accepting files, ensuring changed TOML paths must be
regular files within the repository rather than links followed by
Path.is_file().

In `@pyproject.toml`:
- Line 14: Update the Taplo dependency declaration in the project configuration
so Linux aarch64 development installs use an available binary or compatible
package source instead of falling back to the broken taplo 0.9.3 sdist. Preserve
Taplo functionality and the existing dependency configuration style.
