- combine the worker-lite performance and reliability work into one coherent commit for the cf-worker branch
- reduce duplicate submissions and repeated settings fetches on the frontend, add clearer saving/recognition states, and keep Worker-limit error messaging focused on real failures
- refactor worker hot paths around D1/KV usage with short-lived caching, lighter settings/auth access, lazy Prisma creation, slimmer statistics/calendar queries, and safer exchange-rate reads
- simplify logo search and remote-logo handling for Lite constraints, keep cron and notification flows aligned with Worker Free limits, and preserve current Lite-specific UX decisions
- remove unsupported Prisma interactive transactions for D1, batch Wallos import writes, chunk D1 tag joins, and fix Cloudflare-specific issues such as KV minimum TTL handling and remote reset execution on Windows
- include the latest Lite-side cleanup: route-level tags caching, skipping unnecessary tag reads in statistics when tag budgets are disabled, removing calendar adjacent-month prefetching, and executing remote reset SQL through a temp file
