PR Summary

Low Risk
Dependency-only version bump with no code edits; risk is limited to possible minor-version API or parsing changes in hifijson affecting JExpr lexing.

Overview
Bumps the workspace dependency hifijson from 0.4.0 to 0.5.0 in Cargo.toml and refreshes the matching entry in Cargo.lock. No application or library source is changed in this PR.

The only in-repo consumer is hashql-syntax-jexpr, which uses hifijson (with the alloc feature) for JSON string handling in the JExpr lexer. Behavior there should stay the same unless the minor release introduces API or parsing differences worth checking against existing lexer tests.

Because hifijson is still in 0.x, a minor bump (0.4 → 0.5) can include breaking API/behavior changes; it’d be good to ensure any JSON parsing/serialization call sites and related tests still cover edge cases after this upgrade.

Footnotes

1. 24 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

2. No successful run was found on main (a6674c8) during the generation of this report, so c84546d was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩
