docs/readme.md and docs/troubleshooting.md were removed in #248 (released in 1.8.4) as out of date, but the Databricks documentation for the Node.js driver still links to both under "Additional resources", so those links return 404. GitHub redirects the blob/master/... links to main, so restoring the files at the same lowercase paths fixes the links.

The old content described the Hive-era API and a reconnect-on-close recipe that no longer applies, so both pages are rewritten for the current 3.x driver. The getting-started page is a short tour that points to the README, CONNECTION_PARAMETERS.md, and the examples. The troubleshooting page covers DBSQLLogger, the errors you see for common failures on each backend, connection settings, auth, proxies, TLS, timeouts and retries, and the kernel native module. The README now links to both pages.

Every behavior and message the pages document was checked against lib/ and observed against a live warehouse on both Thrift and useKernel: true: invalid token, wrong path, unknown host, SQL errors, STATEMENT_TIMEOUT, half-supplied mTLS, logging, the proxy option with and without auth, and HTTPS_PROXY (ignored by Thrift, honored by Kernel). TLS was checked locally against a server signed by a private CA: default verification fails, and customCaCert or checkServerCertificate: false fixes it on both backends; NODE_EXTRA_CA_CERTS works only on Thrift. socketTimeout was also checked locally. Most of the same checks were repeated against the published 3.0.0. There, Thrift errors expose the SQLSTATE only as error.response.sqlState, which the page notes. The DBSQLLogger directory handling that hasn't been released yet is left out.

Docs only, with no runtime change. npm run lint, type-check, build, and npm test (1527 passing) pass. prettier --check passes for every file in the repo. npm pack --dry-run shows docs/ is still excluded from the package, like the existing docs/TELEMETRY.md.

Fixes #274
