Add bilingual JSON-library analysis reports (EN/DE)

[Easton97-Jens]

Motivation

• Provide a repository-specific, in-depth analysis to decide which JSON library best fits this codebase, including benchmark validity and per-library guidance.
• Fulfill the request to produce two matching outputs (ANALYSIS_EN.md and ANALYSE_DE.md) with identical technical content in English and German.
• Document facts extracted from code (integration, parsing model, build wiring) and clearly separate facts, inferences, and uncertainties to guide engineering decisions.

Description

• Added ANALYSIS_EN.md containing a full English analysis covering repository overview, library usage, benchmark validity, per-library evaluation, test05.json discussion, multi-criteria evaluation, final recommendations, and a comparison table.
• Added ANALYSE_DE.md which is the German translation of the same analysis with matching structure and table.
• Both files explicitly note that YAJL is the only JSON library integrated in this repository, call out benchmark-methodology issues, and provide concrete recommendations and to-dos for fair cross-library benchmarking and correctness testing.
• Committed both files and created the PR metadata (commit message and PR body) to add these reports to the repository.

Testing

• No automated unit or CI tests were run against the codebase as part of this change.
• Performed repository-level verification commands to validate the change and file contents: git status, wc -l ANALYSIS_EN.md ANALYSE_DE.md, and nl -ba ANALYSIS_EN.md | sed -n '1,260p' / nl -ba ANALYSE_DE.md | sed -n '1,260p', and created a commit to record the added files (all succeeded).
