build: migrate from tsup to rslib

Replace tsup (esbuild-based) with rslib (rspack-based) across all packages.

tsup's built-in nodeProtocolPlugin strips the 'node:' prefix from all
Node.js builtins. Unlike node:fs etc., node:sqlite has no unprefixed
form, causing ERR_MODULE_NOT_FOUND at runtime. rslib handles node:
imports correctly without any workarounds.

Changes:
- Replace tsup.config.ts with rslib.config.ts in core, daemon, cli
- Swap tsup → @rslib/core in devDependencies
- Fix log-store.ts params type (Record<string, unknown> → Record<string, string | number>)
- Fix logStream.fd type cast in start.ts
- Exclude __tests__ from CLI tsconfig to avoid DTS errors
- All 356 tests pass, nerve init works correctly

Closes #70
