Sync conflict error message is hard to decipher

If you write to local and remote database at the same time, sync sometimes gives you the following error instead of explicitly saying there's a conflict:

Error: Sync(InvalidPushFrameNoLow(8, 7))
    at Database.sync (/Users/penberg/src/tursodatabase/libsql-js/index.js:106:29)
    at Sqlite3Client.sync (file:///Users/penberg/tmp/example/node_modules/@libsql/client/lib-esm/sqlite3.js:148:41)
    at example (file:///Users/penberg/tmp/example/foo.mjs:15:14)
    at file:///Users/penberg/tmp/example/foo.mjs:40:1
    at ModuleJob.run (node:internal/modules/esm/module_job:195:25)
    at async ModuleLoader.import (node:internal/modules/esm/loader:336:24)
    at async loadESM (node:internal/process/esm_loader:34:7)
    at async handleMainPromise (node:internal/modules/run_main:106:12) {
  code: ''
}

Node.js v18.19.0

The report points to Database.sync in libsql-js/index.js:106 and Sqlite3Client.sync in sqlite3.js:148; begin by reproducing the sync call from foo.mjs:15 and tracing the reported error. Confirm that the resulting message identifies the conflict rather than only exposing the internal error name, then verify the behavior through the relevant sync path.
