Summary

Reuse highlighted code across builds through a shared persistent cache, reducing repeated Shiki work while preserving generated output.

Performance

Full frontend site publishing is now approximately 2× faster, completing in 15 seconds instead of 30 seconds.

Changes

• Add PersistentCache to ts-util-node with buffered JSON shards, atomic writes, inter-process locking, bounded memory, and idle-entry cleanup.
• Cache standard Shiki output by source, language, themes, and dependency version; initialize Shiki only on a cache miss.
• Add --no-cache and options.cache: false for highlighting and image optimization.
• Support optional highlighter flushing after build and development batches, including failures. Include final flushing in completion timing.
• Update Regor to 1.7.6 consistently across packages.
• Document cache usage, plugin responsibilities, and CLI behavior in package READMEs and frontend guides.

Validation

• All 1,151 tests across 115 files passed.
• TypeScript, plugin contract checks, lint, dependency consistency, line endings, and whitespace checks passed.
• All 18 distributable packages built and verified.
• Compiled CLI fixtures verified cold, warm, and uncached runs, with identical CSS and HTML differing only in existing stylesheet timestamps.
