chore: Bump serde/serde_yml/serde_width

[dependabot]

Bumps serde_with from 3.18.0 to 3.21.0.

Release notes

Sourced from serde_with's releases.

serde_with v3.21.0

Security

• GHSA-7gcf-g7xr-8hxj: KeyValueMap serialization panics on empty sequence or map entries Bad or attacker controlled values could cause a panic while allocating too large values. Fixed in #966 by setting a maximum allocation size during the creation of collections like Vec or sets.

  Thanks to @​7thParkk for reporting the issue.

Added

• Add NoneAsZero adapter that maps Option<NonZero*> to a plain integer, encoding None as 0 by @​SAY-5 (#486)

Changed

• Re-enable link-to-definition on docs.rs (#964)

Fixed

• Fix some doc links to point to the correct types (#963)
• Re-enable unused_qualifications and fix the resulting findings by @​lms0806 (#962)

serde_with v3.20.0

Added

• Add support for base58 encoding, similar to the existing base64 setup by @​mitinarseny (#943)

Fixed

• Extend base64 with schemars support by @​mitinarseny (#9949)

serde_with v3.19.0

Added

• Add support for hashbrown v0.17 (#940)

  This extends the existing support for hashbrown to the newly released version.

Review

Verdict: LGTM — routine Dependabot bump of serde_with from 3.18.0 → 3.21.0 across three Cargo.lock files. No Cargo.toml changes; version constraint remains satisfied.

Details

• Reviewed changed files
• Assessed risk

Scope: lockfile-only bump in packages/cubejs-backend-native/Cargo.lock, rust/cube/Cargo.lock, rust/cubesql/Cargo.lock.

Notable upstream changes (3.18.0 → 3.21.0):

• Security fix — GHSA-7gcf-g7xr-8hxj: KeyValueMap panic on empty sequence/map entries from attacker-controlled input. Cube doesn't appear to use KeyValueMap, so this is defense-in-depth.
• Minor additions (NoneAsZero, base58, hashbrown v0.17 support) — additive, no breaking changes.
• All 3.x releases are semver-compatible.

Findings: none. Safe to merge once CI is green.

• Branch: `dependabot/cargo/rust/cube/serde_with-3.21.0`
