Add up-to-date SonarCloud + architecture reanalysis report for PR #3540

[Easton97-Jens]

Motivation

• Provide an up-to-date, fully enumerated SonarCloud reanalysis and architecture review for PR Prototype 2: Evaluating alternatives to YAJL for JSON processing owasp-modsecurity/ModSecurity#3540 to support code review and remediation planning.
• Analysis is explicitly based on commit 3ec86cf63e095cddf4f22f6d9cfe3461bbbf4942 and verified against the SonarCloud PR analysis for that same SHA.
• Focus the inspection on the JSON backend area and the build/configuration-time backend selection to surface backend-specific findings and architectural coupling.

Description

• Add the report file analysis/pr3540_sonar_architektur_neuanalyse.md containing: commit verification, Quality Gate conditions, a full enumerated table of Sonar issues (paginated), a separate table of open issues, summary statistics, JSON-backend focused findings, an architecture evaluation, and concrete minimal fix suggestions.
• The architecture section documents evidence from configure.ac, src/Makefile.am, src/request_body_processor/json_adapter.cc, and src/request_body_processor/json_backend.h showing compile-time backend selection and a shared interface.
• The Sonar data in the report was retrieved live via SonarCloud APIs and GitHub PR APIs and is presented with explicit source links and stated analysis limits.

Testing

• Collected and validated data using the SonarCloud and GitHub APIs with commands such as curl 'https://sonarcloud.io/api/project_pull_requests/list?project=owasp-modsecurity_ModSecurity', curl 'https://sonarcloud.io/api/qualitygates/project_status?projectKey=owasp-modsecurity_ModSecurity&pullRequest=3540', and the paginated issues endpoint curl 'https://sonarcloud.io/api/issues/search?componentKeys=owasp-modsecurity_ModSecurity&pullRequest=3540&ps=100&p=1&additionalFields=_all', all of which returned expected API responses for the PR.
• Ran a local Python pagination script to enumerate all Sonar issues and generate analysis/pr3540_sonar_architektur_neuanalyse.md, and used file inspections (nl -ba, rg) to collect configuration and source facts referenced in the report.
• Verification results recorded in the report include the Quality Gate status and the fact that Sonar data and hotspots were retrievable for the analyzed PR, and the report file was produced successfully at analysis/pr3540_sonar_architektur_neuanalyse.md.

Provide rule-correct remediation for cpp:S6009

This row maps cpp:S6009 to "Grenzfallprüfung ... Null-/Range-Checks", but the same report defines the actual Sonar problem as replacing const std::string& with std::string_view (see section 4). If reviewers follow this fix plan, the Sonar issue will remain unresolved after re-scan, which undermines the report’s stated remediation purpose.
