Add native SQL formatting with rtree format

[rmorehig]

Add rtree format to format complete SQL through POST /v1/query-format without executing SQL. Both rtree query and rtree format accept positional SQL, --sql, --query, and -q. Omitted SQL or - reads stdin, including shell file redirection and cat pipes. Supplying multiple SQL arguments is rejected.

rtree format "select 1"
rtree format -q "select 1"
rtree format --query "select 1"
rtree format --sql "select 1"
rtree format < query.sql > formatted.sql
cat query.sql | rtree format

rtree query "SELECT 1"
rtree query -q "SELECT 1"
rtree query --query "SELECT 1"
rtree query --sql "SELECT 1"
rtree query < query.sql
cat query.sql | rtree query

Explicit stdin also works as a positional -, --sql -, --query -, or -q - for both commands.

Formatting preserves the complete response byte for byte; --json returns { "formatted": "..." }. Organization, cluster, and optional database use existing scope resolution. The shared stdin reader preserves whitespace. Formatting allows 120 seconds for the complete HTTP request; the API retains its 30-second formatting timeout, 50 MiB JSON input limit, and 100 MiB output limit. Multiple statements and literals are preserved, including inline INSERT VALUES payloads without completeness/schema validation. Errors emit no partial formatted SQL.

Bump CLI 0.6.14 → 0.6.15 in Cargo.toml and Cargo.lock.

Dependency: Platform #1468, inspected at 397dc652846ad5820073641c19301ea154289cce. The formatting endpoint must be deployed before this command can be used.

Validation:

• cargo fmt --all -- --check; cargo test --locked: 208 passed, six existing real-Platform tests skipped locally.
• cargo clippy --all-targets --locked: succeeded with pre-existing warnings.
• Integration tests verify all SQL input forms on both commands, conflicting inputs, exact request bodies and scope, complete SQL/output, large stdin, API errors, and malformed responses.
• Executable HTTP fixture proof: 20 command invocations, covering every inline form, actual file redirection, and cat pipes with implicit stdin and every explicit - form. SQL bytes, endpoints, scope, output, and generated help verified.
• Formatter feature validation also covered an exact 10 MiB stdin round trip, active-request cancellation on SIGINT, and a response after 31 seconds. Against the existing local Platform #1468 stack: multiple statements, incomplete inline INSERT VALUES data, a 270,000-element IN list, and syntax errors.
• Codex autoreview (--mode local --max-priority P3) and thermo-nuclear maintainability review: no actionable findings. TruffleHog clean.

Companion: MCP #32.

Note

Low Risk
CLI-only feature and input UX changes with mock integration tests; depends on a new platform endpoint but does not alter auth or query execution paths beyond shared SQL resolution.

Overview
Adds rtree format to pretty-print SQL via POST /v1/query-format (optional database scope), with plain stdout or --json, and a 120s HTTP timeout so upload/download does not eat the server’s formatting budget.

query and format now share richer SQL input: --sql / --query / -q, implicit or explicit stdin (-), and stdin content is sent without trimming so whitespace is preserved. The API client exposes post_with_timeout for configurable request deadlines.

Docs cover the new command and limits; integration tests exercise format, stdin, scopes, and errors. Version 0.6.14 → 0.6.15 (requires Platform /v1/query-format).
