Fix size=0 query parameter to return all floors instead of default 30

[Copilot]

The API endpoint /api/holes/{hole_id}/floors?size=0&offset=0 was returning only 30 floors instead of all floors. The validation framework applies a default value of 30 when size=0 is passed, preventing the special case from being detected.

Changes

• apis/floor/apis.go: Check raw query parameters before validation to detect explicit size=0&offset=0 and pass nil to MakeQuerySet for unlimited results
• tests/floor_test.go: Add test case verifying all 50 test floors are returned
• .gitignore: Add treehole_next binary

Example

// Before: validation converts size=0 to size=30
var query ListModel
err = common.ValidateQuery(c, &query)  // query.Size now = 30

// After: check raw params first
rawSize := c.Query("size")
rawOffset := c.Query("offset")
if rawSize == "0" && rawOffset == "0" {
    querySet, err = floors.MakeQuerySet(&holeID, nil, nil, c)  // No limit
}

This matches the existing behavior in ListFloorsOld for backward compatibility.

Pull request overview

This PR fixes a bug where the API endpoint /api/holes/{hole_id}/floors?size=0&offset=0 was incorrectly returning only 30 floors instead of all floors. The issue occurs because the ListModel schema has a default:"30" tag that causes the validation framework to replace size=0 with the default value of 30, preventing the special case logic from detecting the request for all floors.

Key Changes:

• Added raw query parameter checking before validation to detect explicit size=0&offset=0 requests
• Updated ListFloorsInAHole to pass nil for both offset and size to MakeQuerySet when the special case is detected, returning all floors without limit
• Added test case to verify all 50 test floors are returned with size=0&offset=0 parameters
