chore(deps): update rust crate chrono to v0.4.45

[wesbillman]

Why

Renovate #1050 (chrono 0.4.44 → 0.4.45) fails the Windows Rust clippy job: could not compile wmi (lib) due to 16 previous errors.

Root cause: chrono 0.4.45 bumps its windows-link requirement to ^0.2, and cargo's re-resolution during renovate's cargo update chrono also collapsed unrelated duplicate windows crates downward — iana-time-zone and wmi dropped from windows-core 0.62.2 to 0.61.2, and generator dropped to windows-link 0.1.3/windows-result 0.3.4. wmi 0.18.4 doesn't compile against the older windows-core interface traits.

What

Same chrono bump, minus the collateral downgrades (Cargo.lock only):

• chrono 0.4.44 → 0.4.45
• generator 0.8.8 → 0.8.9 (restores windows-link 0.2.1 / windows-result 0.4.1)
• iana-time-zone and wmi kept on windows-core 0.62.2 — both requirements allow it (>=0.56, <=0.62 and >=0.59, <0.63)

Supersedes #1050; renovate will detect 0.4.45 on main and close it.

Verification

• Reproduced chore(deps): update rust crate chrono to v0.4.45 #1050's exact bad diff locally via cargo update chrono --precise 0.4.45
• cargo metadata --locked passes — lockfile self-consistent
• cargo clippy --workspace --locked clean locally (macOS); the Windows clippy job on this PR's CI is the authoritative check for the original failure

Closing in favor of #1532: renovate #1050 merged first, so main already has chrono 0.4.45 — the remaining defect is the windows-* downgrade, which #1532 repairs directly on top of main. Same end-state as this PR, right base.
