Set XY's competitive product north star

[Alek99]

Summary

• Position XY around an explicit ambition to become the fastest and most customizable Python charting library across every chart family and every data scale, from a handful of values to billions of rows.
• Make that ambition a repository-wide product north star for agents and contributors: every competitor lead is a product gap, backed by reproducible benchmarks, raw results, capability coverage, and visual examples.
• Expand the roadmap beyond a 2D-only destination to include geographic, 3D, and volume visualization.
• Remove the public-claim guardrail checker, tests, CI wiring, Make targets, and wording-policy sections.

Why

The existing README primarily positioned XY as a large-data 2D specialist. This change makes the intended destination unmistakable: one charting system for ordinary and massive datasets, any chart family, leading performance, and complete design control. The benchmark program becomes the evidence system for proving progress against every relevant competitor rather than one favorable scatter workload.

Summary by CodeRabbit

• Documentation
  • Refreshed the README with clearer product positioning, customization highlights, performance context, and a broader chart roadmap.
  • Added roadmap coverage for geographic, 3D, and volume visualizations.
  • Clarified performance guidance for large datasets and benchmark methodology, including rendering modes and reproducibility details.
  • Updated contribution and production-readiness guidance, including accessibility and cross-browser verification expectations.
• Chores
  • Streamlined local and CI verification by removing claim-specific checks and related documentation.

📝 Walkthrough

Walkthrough

The PR removes claim-guardrail tooling and its CI, Makefile, verification, packaging, and test integrations. It also revises benchmark evidence guidance, product positioning, staged roadmap documentation, contribution requirements, and production-readiness checks.

Changes

Claim evidence and product documentation

Layer / File(s)	Summary
Remove claim-guardrail execution .github/workflows/ci.yml, Makefile, scripts/verify_local.py	Claim-guardrail execution, selection, and benchmark-harness coverage are removed from CI and local verification.
Align verification and contribution checks scripts/verify_ci_workflow.py, scripts/verify_sdist.py, tests/test_verify_*.py, docs/api-reference/contributing.md, spec/process/contributing.md	Verification expectations, tests, package manifests, and contribution guidance are updated for the removed guardrail and renamed “Competitive Evidence” guidance.
Revise benchmark evidence documentation README.md, docs/overview/benchmarks.md, spec/benchmarks/*, CLAUDE.md	Benchmark methodology and results now document rendering modes, reproducible comparison metadata, broader workloads, and competitive evidence.
Update positioning, roadmap, and readiness documentation README.md, docs/advanced/index.md, docs/core-concepts/large-data-and-performance.md, spec/README.md, spec/api/chart-roadmap.md, spec/process/production-readiness.md	Product messaging shifts to staged chart coverage and broader customization, while readiness documentation adds accessibility details and removes claim-guardrail gates.
