Issue 29: cross-repository quality policy and context accuracy

[DerekCorniello]

Local Derek-authored remediation stack for issue 29. Adds scoped encoding/documentation policy, generated-artifact contracts, repository maps, guidance accuracy, and context checks.

[greptile-apps]

Greptile Summary

The PR introduces a data-driven documentation and encoding quality gate while updating cross-repository architecture, ownership, governance, and artifact-generation guidance.

• Runs local Markdown-link, UTF-8, and scoped ASCII validation in CI.
• Defines repository-specific encoding scopes and generated-artifact contracts.
• Updates ecosystem maps and decisions for source-pinned runtime consumption, syntax ownership, and the examples repository.
• Corrects the previously reported encoding-precedence and linked-image parsing issues.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains; the current code resolves all three previously reported documentation-checker issues.

Important Files Changed

Filename	Overview
scripts/ci/check-docs.py	Implements tracked-file UTF-8 checks, scoped ASCII enforcement, and local Markdown-target validation; the displayed prior parser and precedence defects are corrected.
scripts/tests/test_check_docs.py	Adds focused regression coverage for encoding-policy validation, root glob matching, overlapping ASCII scopes, and linked-image targets.
docs/encoding-policy.json	Defines validated per-repository ASCII scopes and documented Unicode allowances.
.github/workflows/sonar.yml	Adds the documentation quality checker to the workflow lint job.
docs/generated-artifacts.yml	Records generated artifacts together with their source, pinned producer, regeneration command, and drift check.
AGENTS.md	Reframes repository guidance around ownership accuracy, scoped encoding rules, and the new documentation quality gate.
ARCHITECTURE.md	Updates the ecosystem map with mux-examples, mux-context, and the canonical shared syntax-matrix location.
