Fix: $gt/$lt bounds outside schema min/max incorrectly exclude boundary documents

[Copilot]

When a numeric query bound falls outside the schema's minimum/maximum, getNumberIndexString() clamps it to the boundary value — producing the same index string as the boundary document. An exclusive scan ($gt/$lt) then skips that document even though it should match.

// schema: score { minimum: 0, maximum: 100 }
// $gt: -10 should match score=0, but was excluding it
{ selector: { score: { $gt: -10 } } }  // missing { id: 'aa', score: 0 }
{ selector: { score: { $lt: 110 } } }  // missing { id: 'ee', score: 100 }

Changes

• src/query-planner.ts — After resolving matcherOpts for a numeric index field, check if startKey < schema.minimum or endKey > schema.maximum. In those cases, promote the exclusive bound to inclusive, since clamping makes the boundary index string identical to the boundary document's. Bounds exactly at minimum/maximum are left exclusive as expected.

• test/unit/rx-storage-query-correctness.test.ts — Added testCorrectQueries covering all four edge cases: $gt below min, $lt above max, $gt exactly at min (must still exclude), $lt exactly at max (must still exclude).

@copilot check if this test really fails without the fix, if yes show me the failing console output

Yes, the test fails without the fix. Here's the console output:

WRONG QUERY RESULTS FROM RxStorageInstance.query(): $gt below the schema minimum must include the minimum document
{
    "resultIds": [ "bb", "cc", "dd", "ee" ],
    "expectedResultDocIds": [ "aa", "bb", "cc", "dd", "ee" ],
    ...
}

Document { id: 'aa', score: 0 } is missing from the results. The query { score: { $gt: -10 } } should return all 5 documents, but score=0 (the schema minimum) is excluded because getNumberIndexString() clamps -10 to 0, and the exclusive $gt scan then skips the document at index position 0.
