• test: add failing tests for StateManager lock and cleanup bugs

• 8 test methods covering BUG-01 (missing LOCK_UN), BUG-02 (callback exception leaks), REF-01 (no try-finally)
• Baseline tests for startRun/completeRun functionality
• Lock verification helper using LOCK_EX|LOCK_NB non-blocking check
• 2 structural tests fail against current code (RED phase), proving missing try-finally

• fix: add try-finally to StateManager for proper lock and handle cleanup

• BUG-01: flock(LOCK_UN) now always called before fclose via finally block
• BUG-02: $completeRun() callback moved after lock release, exceptions cannot leak locks
• REF-01: both startRun() and completeRun() use try-finally pattern
• Added fopen return value checks for defensive error handling
• All 110 tests pass with no regressions

• fix: replace loose equality, fix method typo, and resolve variable shadowing in API clients

• Replace all == with === in ApiClientV1 (4 locations) and ApiClientV2 (1 location)
• Rename covertToModel to convertToModel in ApiClientV2
• Fix $step variable shadowing in convertStep() foreach using $childStep

• refactor: extract shared host URL resolution into protected methods

• Add resolveApiHost() and resolveAppUrl() protected methods to ApiClientV1
• Refactor ApiClientV1 constructor to use new methods instead of inline logic
• Refactor ApiClientV2 constructor to use inherited resolveApiHost('v2')
• Eliminates duplicated URL construction logic between V1 and V2 clients

• refactor: add isDebug() to LoggerInterface and guard json_encode in debug calls

• Add isDebug() method to LoggerInterface contract
• Implement isDebug() in Logger returning the debug flag
• Guard 3 json_encode calls in ApiClientV1 and ApiClientV2 with isDebug() check
• Prevents expensive serialization when debug mode is inactive

• refactor: extract tryApiCall helper and cache attachment file sizes

• Add tryApiCall() private method for standardized error handling across 9 methods
• Refactor isProjectExist, getEnvironment, completeTestRun, isTestRunExist,
  getConfigurationGroups, createConfigurationGroup, createConfigurationItem,
  runUpdateExternalIssue, enablePublicReport to use tryApiCall()
• Keep createTestRun and uploadAttachment with their own error handling
• Modify filterValidAttachments to return {attachments, sizes} structure
• Modify splitIntoBatches to accept pre-computed sizes, eliminating redundant
  filesize()/strlen() calls

• test: add failing tests for external link order independence and dead method removal

• Add testExternalLinkFromEnvBothVarsSet to verify external link assembly regardless of env var order
• Add testExternalLinkFromEnvOnlyTypeNoUrl to verify partial env vars produce no link
• Add testNoResetConfigurationCacheMethod to verify dead method is removed from TestOpsReporter

• test: add failing tests for null reporter fallback and scoped error_reporting

• Test runFallbackReporter with null primary reporter (BUG-03)
• Test fallback activation with null primary (BUG-03)
• Test error_reporting not globally suppressed (REF-04)

• fix: resolve external link env var order bug, tighten permissions, rename method, remove dead code

• Fix ConfigLoader external link assembly to be order-independent via post-loop finalizeExternalLink()
• Change mkdir permissions from 0777 to 0755 in Logger and FileReporter
• Rename prepare_report_folder to prepareReportFolder in FileReporter
• Remove unused resetConfigurationCache method from TestOpsReporter

• fix: null-safe fallback reporter and scoped error_reporting suppression

• Add null check for primary reporter in runFallbackReporter() before
  calling getResults(), preventing NPE when reporter is null (BUG-03)
• Remove global error_reporting(E_ALL & ~E_DEPRECATED) at file scope
• Add save/restore error_reporting pattern with finally blocks to all
  five methods: startRun, completeRun, addResult, sendResults,
  runFallbackReporter (REF-04)
• Fallback reporter activates regardless of primary reporter state

• fix: use Step structured API for status mapping and remove deprecated setAccessible calls

Step status mapping was writing to dynamic properties via BaseModel::__set
instead of Step->execution, so mapped statuses were never sent to the API.
Also remove setAccessible() calls deprecated since PHP 8.1.

• chore: bump version to 2.1.15 and update dependencies

Update guzzlehttp/psr7 2.8.0→2.9.0, qase-api-client 1.1.5→1.1.8,
qase-api-v2-client 1.1.2→1.1.3.

• fix: make error_reporting test check source code instead of runtime state

The test checked runtime error_reporting() level which depends on the CI
environment's php.ini, making it fail when E_DEPRECATED is already
suppressed. Now checks that CoreReporter.php has no file-scope
error_reporting() call.

• fix: restore setAccessible() calls required for PHP 8.0 compatibility

setAccessible() is a no-op since PHP 8.1 but still required on PHP 8.0
to access private properties/methods via Reflection.
