build(deps): bump the jiff group with 2 updates

[dependabot]

Bumps the jiff group with 2 updates: jiff and jiff-static.

Updates jiff from 0.2.16 to 0.2.18

Changelog

Sourced from jiff's changelog.

0.2.18 (2026-01-05)

This release ships a sizeable refactor to the RFC 2822, RFC 9110, RC 3339, RFC 9557, ISO 8601 and friendly format printers. Specifically, they are now all monomorphic internally (instead of being generic over jiff::fmt::Write) and write to uninitialized buffers. This improves runtime performance (sometimes dramatically so), and to a more modest degree, decreases binary size and improves compile times.

This release also includes a bug fix where DateTime::MIN.to_zoned(..) could panic.

Enhancements:

• #460: Improve runtime performance and binary size of RFC 2822 printer.
• #461: Tweak behavior of printing min/max offsets in RFC 2822 and Temporal printers.
• #462: Export fallible constructors for jiff::SignedDuration.
• #465: Improve runtime performance and binary size of the "friendly" duration printer.
• #468: Improve runtime performance and binary size of the Temporal ISO 8601 duration printer.
• #470: Improve runtime performance and binary size of the Temporal ISO 8601 datetime printer.
• #474: Improve runtime performance and binary size of Jiff's strftime implementation.
• #477: Fix a bug where time zone lookups for civil::DateTime::MIN could panic.

0.2.17 (2025-12-24)

This release contains binary size improvements to Jiff, more succinct error messages and some new minor APIs.

While Jiff 1.0 is overdue, I've been doing a lot of experimenting with improving Jiff's binary size and compile times. In particular, I want to spend time doing this before Jiff 1.0 so that we don't box ourselves into a corner. (For example, some binary size improvements may require minor API breaking changes.)

In this release, Jiff has switched to structured error handling internally in an effort to provide error predicates and also hopefully improve binary sizes and compile times. Overall this didn't have as big of an impact on binary sizes or compile times as I was hoping. I did take this opportunity to
