Add without for configured eager loads

[elpete]

Closes #48

Issue review

Recommendation: 9/10 — implement. Automatic eager loading is useful as an entity default, but individual queries need a straightforward escape hatch to avoid unnecessary joins/queries or large relationship graphs. This mirrors the control Quick already provides for global scopes. The only meaningful downside is another query-builder state operation to understand.

Implementation

• adds .without() to clear all configured eager loads
• adds .without(nameOrArray) to remove selected eager loads
• removes nested branches when their parent is excluded
• supports both string eager loads and callback-configured eager loads
• remains chainable, so callers can remove defaults and add different explicit eager loads afterward

Test-first evidence

The public regression initially errored with QuickMissingMethod. It now disables the automatic comments eager load on EagerLoadedPost, confirms the relationship is not loaded, confirms lazy-loading protection fires, and confirms only the base posts query runs.

Validation

• focused EagerLoadingSpec: 28 passed, 0 failed, 0 errors
• full Lucee 6 suite: 496 passed, 0 failed, 0 errors, 3 skipped
• box run-script format
• git diff --check
