fix: bump openjd-rs crate deps to 0.3.0/0.5.0/0.5.0

Bump Rust crate dependencies to pick up wrap-action bug fixes:
- openjd-expr 0.2.1 -> 0.3.0
- openjd-model 0.4.0 -> 0.5.0 (resolves 0.5.1 via semver)
- openjd-sessions 0.4.0 -> 0.5.0 (resolves 0.5.1 via semver)

Adapts range_expr.rs for expr 0.3.0 breaking changes:
- IntRange fields are now private (use accessor methods)
- RangeExpr::from_values returns Result

Updates 3 string-operation-counting test expectations to match
expr 0.3.0's more granular operation budgeting.
