…ling - Add --file flag and stdin support to `dremio query run` so multi-line SQL no longer requires shell escaping (supports --file path, piped stdin, and '-' argument) - Enrich 401 errors with a region hint when the default US endpoint is used, saving EU users from a confusing debugging loop - Put breadcrumb comment on its own line so SQL with -- inline comments is no longer swallowed by the prepended comment - Show config file path and region info in `dremio setup --help` Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Address review feedback: leverage typer's exists/file_okay/dir_okay/ readable/allow_dash options instead of manual checks. This gives proper error messages for directories, missing files, and unreadable files out of the box, and simplifies the input resolution logic.

Summary
Addresses CLI feedback from a marketing data engineer building a semantic layer with Dremio Cloud EU + Claude Code:
--fileand stdin support fordremio query run— Multi-line SQL (CREATE VIEW, CTEs) no longer requires shell escaping. Supports--file query.sql, piped stdin, anddremio query run -for reading from stdin.api.dremio.cloud), the error now suggests checking the EU endpoint. Previously took ~45 min to diagnose.--SQL comments being swallowed — The breadcrumb comment (/* dremio-cli: submitter=cli */) is now on its own line, so--inline comments in user SQL no longer comment out the rest of the query.dremio setup --help— Help text now shows where the config file is written and that region (US/EU) is prompted.Test plan
dremio query run "SELECT 1"— inline arg still worksdremio query run --file query.sql— reads and executes SQL from fileecho "SELECT 1" | dremio query run -— reads from stdindremio query runwith no args — shows helpful errordremio query run --file missing.sql— shows file-not-found errordremio query run "-- comment\nSELECT 1"— comment doesn't break querydremio setup --helpshows config file path and region info🤖 Generated with Claude Code
