test: support full-null relationship coverage

[elpete]

Closes #154

Issue review

Recommendation: 10/10. Empty relationships must behave correctly with full null support on every supported CFML engine. Null mode is an engine-level compatibility setting, and Quick should preserve the same relationship semantics in either representation.

Reasons for:

• A missing foreign key is normal relationship state, not an exceptional condition.
• Quick and qb should accept a real null anywhere a partial-null runtime previously supplied an empty string.
• Full-null coverage belongs in the regular CI matrix so future regressions cannot silently return.

Tradeoffs:

• Full-null and partial-null modes intentionally expose different raw values. Tests should assert public semantics where possible and narrowly normalize representation only when snapshots are testing another concern.
• Doubling the stable matrix increases CI runtime, but it validates a materially different runtime mode.

Reproduction review

On Lucee 6 with full null support and qb 14.0.0-beta.3, the original public flow getInstance( "Post" ).find( 7777 ).getAuthor() returns null without throwing. The original Quick/qb exception is fixed upstream.

The expanded full-null suite then exposed missing-key assumptions in Quick and several dependencies. Each dependency fix is maintained as a narrow CI patch here until its upstream PR is merged. Every upstream PR includes at least one public-API regression that fails before its fix.

Implementation

• Reads FULL_NULL in the test application and enables engine null support.
• Runs Lucee 5/6 and BoxLang CFML 1 with both ColdBox 7/8 and full-null true/false.
• Runs Adobe 2021/2023/2025 with both null modes on ColdBox 7 and standard null mode on ColdBox 8. Adobe full-null plus ColdBox 8 currently fails inside its framework dependency graph before Quick loads, so full-null Adobe coverage uses the supported ColdBox 7 pairing.
• Runs native BoxLang 1 with ColdBox 8 in both null modes. ColdBox 7 does not expose compatible native BoxLang metadata, while BoxLang CFML continues to cover ColdBox 7.
• Adds Adobe BE on ColdBox 7 and BoxLang BE on ColdBox 8 as experimental full-null coverage.
• Expands PR, scheduled, and release workflows consistently.
• Keeps every matrix row's fullNull value explicit, including experimental includes, to avoid GitHub expression coercion differences.
• Preserves omitted optional arguments on Lucee 5 full-null mode when qualifying columns and excluding all global scopes. Lucee 5 materializes those omitted arguments as null keys, while newer engines may omit the keys entirely.
• Normalizes the native BoxLang date fixture using date parts so it asserts the same public value despite engine-specific date-mask parsing.

Dependency baseline

The passing matrix resolved the latest compatible packages available during this run:

• ColdBox 8.1.0+34
• TestBox 7.0.0+19
• cbJavaLoader 2.6.0+5
• qb 14.0.0-beta.3 (latest qb@be prerelease)
• str 4.0.2
• mementifier 3.7.0+7
• cfcollection 3.7.1
• cfmigrations 5.1.3

[elpete]

Attempted reproduction: I ran the existing public empty-belongs-to flow on a dedicated Lucee 6.2.8.20 server started with -Dlucee.full.null.support=true and qb 14.0.0-beta.3. getInstance( "Post" ).find( 7777 ).getAuthor() returned null and did not throw, so the original exception no longer reproduces. I then made the surrounding tests representation-independent and verified the entire suite in both full-null and normal modes: each finished with 495 passed, 0 failed, 0 errors, and 3 skipped.
