Rust: Update rust-analyzer to 0.0.352

[github-actions]

Summary

Automated update of rust-analyzer and its ra_ap_* crates from 0.0.347 to 0.0.352 (ra_ap_intern pinned to 0.0.352 to keep all ra_ap_* crates aligned, per rust/updating-rust-analyzer.md), following the process in rust/updating-rust-analyzer.md.

The automated updater script (rust/scripts/update_rust_analyzer.py) got as far as cargo upgrade --incompatible --pinned and then failed because the recursive dependency resolution hit a yanked transitive crate (chacha20 0.10.1, pulled in by rand). This PR manually completes the remaining steps of the documented update process.

Changes

1. Cargo: Upgrade dependencies — Upgraded ra_ap_* crates to 0.0.352 (downgrading ra_ap_intern from the 0.0.353 picked by cargo upgrade down to 0.0.352 so all ra_ap_* crates agree), plus either, clap, serde_with, toml, syn, zstd, rand. Worked around the yanked chacha20 0.10.1 by pinning chacha20 to 0.10.2 in Cargo.lock.
2. Rust: Update rust-analyzer sources — Updated RUST_ANALYZER_SRC_TAG/RUST_ANALYZER_SRC_INTEGRITY in MODULE.bazel to the 2026-09-14 rust-analyzer release matching ra_ap_syntax@0.0.352.
3. Rust: Update fixed toolchain — Bumped FIXED_RUST_TOOLCHAIN (and the matching rustup toolchain install commands in test setup scripts) from 1.97.0 to 1.98.1, the latest stable release preceding the new rust-analyzer version.
4. Bazel: Regenerate vendored cargo dependencies — Re-ran misc/bazel/3rdparty/update_tree_sitter_extractors_deps.sh and bazel mod tidy.
5. Rust: Run codegen — Re-ran bazel run (rust/redacted) The rust-analyzer patch (rust/ast-generator/patches/rust-analyzer.patch) needed a small update since upstream removed the #![allow(clippy::disallowed_types)]line it used to target; the patch was regenerated to match the new upstream file (same effective changes: allow warnings/clippy/rustfmt-skip on the generated modules, make a few generator internalspub`).
   • The new rust-analyzer grammar adds a DocComment node alongside Attr, both now implementing a common AnyAttr supertype. Codegen propagated this into rust/schema/ast.py, rust/ql/lib/rust.dbscheme, and the generated .qll/Rust files (new AnyAttr/DocComment classes and QL library files).
   • The extractor's generated emit_any_attr/emit_doc_comment methods are currently unused (dead-code warning) because upstream hasn't yet wired DocComment into any grammar rule that would call them; this is expected with this rust-analyzer version and not a regression.
6. Rust: Add schema upgrade/downgrade scripts and change note — Since the dbscheme changed (new any_attr union type and doc_comments relation), added upgrade/downgrade scripts via misc/scripts/prepare-db-upgrade.sh --lang rust (both marked compatibility: full, since the change is purely additive and not yet populated by the extractor) and a change note under rust/ql/lib/change-notes/.
7. Rust: Update rust-toolchain.toml to 1.98 — Bumped the local dev channel in rust-toolchain.toml from 1.97 to 1.98 to match the new ra_ap_* MSRV, needed for rust/lint.py (cargo fmt/clippy) to run.

Validation

• cargo check --workspace — passes with the new dependency versions.
• bazel run (rust/redacted) — succeeds (only pre-existing/expected WARNING no test source in ...` messages and the new dead-code warning noted above).
• bazel run (rust/redacted):install — succeeds; the extractor pack builds and installs to rust/extractor-pack.
• rust/lint.py (cargo fmt + cargo clippy --fix -D warnings) — passes on all rust/-related crates it targets, after bumping to the 1.98 toolchain. (Unrelated cargo fmt/clippy drift in shared/yeast-schema and unified/swift-syntax-rs, and a pre-existing clippy::unnecessary_unwrap error in shared/yeast-schema, were verified to already exist on main and were left untouched to keep this diff focused.)
• cargo test --workspace — all tests pass except the pre-existing ast-generator's codegen::grammar::test, which fails on both main and this branch when run outside the Bazel sandbox (it depends on crates/syntax/rust.ungram being injected by bazel run (rust/redacted), and even then relies on a project_root()path only valid under Bazel's runfiles layout); this crate has no dedicated CI job today (onlybazel run (rust/redacted), which passed).

Known limitations / follow-ups for a maintainer

• CI has not run for this PR yet — this PR was prepared and validated entirely locally/offline; its own CI run (once triggered) should be checked, especially the Rust extractor test suite, DCA, and the rust-analyzer-update workflow's own checks.
• Per rust/updating-rust-analyzer.md step 8, DCA with database caching disabled should be run and iterated on if needed — not done here since it requires CI infrastructure.
• The new AnyAttr/DocComment classes are currently unreachable from any concrete extraction path (rust-analyzer's grammar hasn't yet started emitting DocComment nodes in place of/alongside Attr), so no QL tests were added for them; a future rust-analyzer update that actually wires up DocComment may require additional extractor/test work.
• The environment's proxy blocked go.dev/golang.google.cn downloads during bazel mod tidy; this did not prevent the vendored deps regeneration from completing, but a maintainer running this in a different network environment may see different/no such warnings.
