feat(languages): add Swift, Dart, Scala, and Groovy universal evidence

[forhappy]

Summary

• Hard-cut Swift, Dart, Scala, and Groovy onto one AST-first universal-evidence production route each.
• Register compass.swift, compass.dart, compass.scala, and compass.groovy as version 1 Qualifying pipelines.
• Remove the replaced Swift/Dart/Groovy direct publishers, Scala-only generic branches, RawCall paths, Swift member-table compatibility, and broad JVM/native terminal-name fallbacks.
• Add bounded Package.swift, pubspec.yaml, build.sbt, and Gradle/Groovy project evidence.
• Migrate framework boundaries for Vapor, Flutter navigation, BLoC, Riverpod, Play, Gradle, and Spock; Dart contextual conventions now require positive source/manifest activation.
• Add deterministic lifecycle qualification, independent source-oracle providers, pinned manifests, baselines, quality-audit tooling, fixtures, compatibility notes, changelog entries, and current support documentation.

Independent qualification

All three-corpus audits passed the record-count, corpus-diversity, per-relation/capability, precision, Wilson, recall, and zero-critical-violation gates:

Language	Accepted records	Precision	Recall	Critical violations
Swift	61,321	1.000	0.99498	0
Dart	8,457	1.000	0.97044	0
Scala	50,529	1.000	0.97713	0
Groovy	12,311	1.000	1.00000	0

Providers are pinned outside the checkout: SwiftSyntax 603.0.0, Dart Analyzer 8.4.0, scala.meta 4.13.10, and Groovy 4.0.27. Corpus checkouts are immutable, clean, and SHA-pinned by the manifests under tests/qualification/.

Cold, warm, fact-neutral, forced, alternate-checkout, delete, rename, and restore runs were byte-deterministic and within the established performance/RSS gates. Qualification artifacts and provider binaries remain on the mounted target volume and are not committed.

Compatibility

This changes the producer route for the four languages while preserving the versioned graph/evidence contracts. Cache fingerprints and evidence validation require current universal evidence; normal invalidation handles rebuilds. No manual migration is required. Registry state intentionally remains Qualifying; promotion to Qualified is a separate product decision.

Follow-up commit ccdecee9 addresses modularity: the former mixed producer is now evidence/extended/common.rs (generic bounded traversal/validation) with dedicated evidence/extended/{swift,dart,scala,groovy}.rs language profiles and a small dispatch module. The production output and all qualification digests remain unchanged.

Refactor verification: full compass-languages --tests, full compass-resolve --tests, core determinism (13/13), fixture qualification (all byte comparisons true), workspace lib/bin Clippy, product boundary, formatting/diff checks, CLI product tests (8/8), and 27 script tests.
