Why

In a fresh folder, sqlquack convert revenue.sql --schema schema.json, the command on the homepage, exited 2 because no sqlquack.toml was there. Without a policy file, SQLQuack now uses the built-in policy, which refuses every known divergence.

Changes

• convert, function, census and index read the file --policy names, else sqlquack.toml in the current directory, else the built-in policy. The Python API does the same.
• --builtin-policy still chooses the built-in policy, even where a sqlquack.toml exists. A --policy file that doesn't exist, or a policy file that isn't valid, is still a usage error (exit 2).
• The SQ0008 help for the built-in policy no longer names the flag. The README, policy, quickstart and convert pages and the diagnostics reference describe the new default.

Verification

• CLI tests in a temporary folder:
  • Without a policy file, convert, census, index and function run (exit 0), and a CURRENT_TIMESTAMP() statement is refused under the built-in policy.
  • A sqlquack.toml in the folder is still read and allows that statement, and --builtin-policy still refuses it.
  • A missing --policy file and an invalid sqlquack.toml exit 2.
• A census binary test with no policy file.
• A Python API test, checked against the command line.
• make check-ci, make test-rust, make verify-recorded.

Gate on a677aab (based on main 37e3767):

• make check-ci: exit 0
• make test-rust: passed, every suite exit 0
• make python-api: 19 passed
• make verify-recorded: 11,779 cases, 0 pending, 0 unproven, 0 failed; translation-results: 0 regressions, 0 other changes.
• Hygiene scan: clean.
  Main has moved to ab479a1 (docs: pass --builtin-policy where census, function and index examples need it #117). This PR merges main and gets re-gated on the exact head in its landing slot, after fix: type a DATE plus INTERVAL 'n' DAY as TIMESTAMP_NTZ(9) #118.

Landing gate at 05c97e7 (main 50e3efb merged):

• make check-ci: exit 0
• make test-rust: exit 0
• make verify-recorded: 11,793 cases, 0 failed; nothing regressed
• Hygiene scan: clean
• Smoke test in a fresh folder with no sqlquack.toml: sqlquack convert revenue.sql --schema schema.json converts under the built-in default (exit 0), and --policy missing.toml still exits 2.
