fix: nondeterministic generation, cache invalidation, and whitespace churn

[hazre]

fixes #42 #43

Before this, identical inputs could still produce different generated output because parts of analysis, rendering, and cache hashing depended on unordered traversal and HashMap iteration. That could cause commands.ts, types.ts, events.ts, and index.ts to reorder entries or pick up extra blank lines across repeated runs. Events also were not part of the cache state, so events.ts could go stale.

This change sorts analyzer and generator inputs before rendering, makes command and config hashing use a stable order, includes events in cache invalidation, and cleans up TS/Zod template rendering so the generated files keep consistent spacing and do not add random blank lines.

Validated with cargo test and repeated downstream builds confirming the generated output stayed unchanged across runs.

Please change the merge target to the develop branch.

Done. I also noticed that it was still updating the generated files and only updating the timestamp, I've updated it to take that into account + some test cleanup stuff to actually remove the left over files properly.
