[test-enhancer] Add tests for NamingHelper and TokenHelper

[github-actions]

This issue tracks the test files generated by the test-enhancer agent for NamingHelper and TokenHelper, two static utility classes with 0% coverage before this run.

Coverage Before

Class	Coverage Before
CobolToQuarkusMigration.Helpers.NamingHelper	0%
CobolToQuarkusMigration.Helpers.TokenHelper	0%

Test Files Generated

Two new test files were created locally on branch test-enhancer/naming-helper-token-helper but could not be pushed due to missing git credentials in the runner environment.

CobolToQuarkusMigration.Tests/Helpers/NamingHelperTests.cs

34 tests covering:

• ToPascalCase — normal input, separator chars, null/empty/whitespace
• DeriveClassNameFromCobolFile — standard COBOL names, underscore-separated, digit-start, empty/null
• GetFallbackClassName — appends Fallback suffix
• GetOutputFileName — .cs and .java extensions
• IsValidIdentifier — valid identifiers, digit-start, hyphens, spaces
• IsSemanticClassName — semantic suffixes, generic names, null/empty
• ExtractCSharpClassName — valid class, generic class fallback, no class declaration
• ExtractJavaClassName — public class, generic class fallback
• ReplaceGenericClassName — class declaration, constructor calls, same-name no-op

CobolToQuarkusMigration.Tests/Helpers/TokenHelperTests.cs

34 tests covering:

• EstimateTokens — null/empty returns 0, positive count, longer = more tokens
• EstimateCobolTokens — null/empty, positive count
• TruncateToTokenLimit — empty, within limit, exceeds limit, preserve start/end
• TruncateCobolIntelligently — empty, within limit, large content
• CalculateRequestDelay — normal limits, minimum, maximum cap, zero limit
• GetRateLimitSummary — non-empty output
• Constants CharsPerToken and SafetyMargin

All 68 new tests pass. The 15 pre-existing failures in CopilotChatClientTests are unrelated (async disposal issue) and were already failing before this run.

Next Recommended Targets

1. CobolToQuarkusMigration.Chunking.Core.NamingConventionEnforcer — pure logic, no external deps
2. CobolToQuarkusMigration.Helpers.RateLimiter — needs careful async mocking
3. CobolToQuarkusMigration.Helpers.FileHelper — file system interactions, mockable

To Apply

Apply the generated tests manually or re-run the test-enhancer agent (cache memory has been updated to skip already-processed targets).
