PR Summary

Low Risk
Dependency-only minor version bump with no source edits; risk is limited to possible parsing/behavior differences in JSON string lexing inside HashQL JExpr syntax.

Overview
Bumps the workspace hifijson dependency from 0.4.0 to 0.5.0 in Cargo.toml and refreshes Cargo.lock (crate version, checksum, and any resolved dependency edges).

hashql-syntax-jexpr is the direct consumer (lexer JSON string handling via hifijson::str); no application code changes in this PR.

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.
