Summary

This PR resolves discrepancies uncovered during a live manual audit of all rekuiper REST endpoints, aligns Swagger/OpenAPI documentation with runtime behaviors, fixes documentation UI artifacts, overhauls the legacy migration guide into a comprehensive multi-engine modernization guide, and migrates repository and Docker Hub references to the Indus-Stack organization.

Key Changes

1. REST Route Aliases & Query Support (crates/rekuiper-server):

   • Added .route("/config", get(get_configs).patch(patch_configs)) alias alongside /configs to match standard CLI and documentation expectations.
   • Enhanced TagMatchQuery with singular aliases (tag and key) alongside plural forms (tags and keys).
   • Extended tag extraction from JSON values to support single-string fields in addition to arrays.

2. OpenAPI & Swagger UI Synchronized (openapi.json, docs/en_US/public/openapi.json):

   • Added /config path alias with full GET / PATCH operations.
   • Documented complete RuleStatus summary counters (sourceRecordsInTotal, sinkRecordsOutTotal, exceptionsTotal, lastException, last_exception, etc.).
   • Documented /rules/tags/match query parameters for filtering rules by tag and key.

3. Multi-Engine Migration Guide (docs/en_US/operation/migration.md):

   • Overhauled legacy migration notes into a modern edge stream migration guide.
   • Includes side-by-side SQL syntax, rule definitions, and architecture comparisons for migrating from eKuiper, Telegraf, Node-RED, and Vector to rekuiper.

4. Repository & Docker Hub Organization Migration (Indus-Stack & indusstack/rekuiper):

   • Migrated all repository links, clone URLs, and badges across the codebase from ankur-paan/rekuiper to Indus-Stack/rekuiper.
   • Updated official Docker images to indusstack/rekuiper:1.0.0-rc4 and indusstack/rekuiper:latest across documentation, Compose files, and the Helm chart.
   • Upgraded GitHub Actions CI workflow to publish and sync Docker Hub metadata to indusstack/rekuiper.
   • Upgraded status badges to dynamic GitHub Actions runner badges.
   • Corrected Helm chart directory references to deploy/chart/rekuiper.

Verification

• Live Regression Audit: 108/108 endpoint assertions passed with real payloads against a running instance.
• Cargo Format: cargo fmt --all -- --check passed (0 diffs).
• Cargo Clippy: cargo clippy --workspace --all-targets -- -D warnings passed with 0 warnings.
• VitePress Build: npm run build completed cleanly with 0 broken links in 34.33s.
