v0.8.4

Breaking changes:

• loggy-intf:
  • Improved the data model used to encode logged items, including:
    • Representing functions and classes as structured objects instead of just
      strings.
    • Making it possible to encode values with reference cycles.
• webapp-builtins:
  • Simplified naming scheme for preserved log files: Names now always include
    a -<num> suffix after the date.

Other notable changes:

• general:
  • Allow node version 23.
• loggy-intf:
  • Improved "human" (non-JSON) log rendering, including:
    • Correctly rendering shared references.
    • Tweaking the styling for readability.
• structy:
  • Started allowing any object (plain or not) to be used as the argument to the
    BaseStruct constructor.
  • Added the option to allow undeclared properties to be dynamically vetted
    instead of always getting rejected, via two additional _impl* methods.
• valvis:
  • BaseValueVisitor:
    • Simplified detection of reference cycles.
    • Added argument isCycleHead to _impl_shouldRef(), so client code can
      choose to be more cycle-aware.
