feat(api-client): REST API client with Postman/Insomnia/Swagger import

[slaveofcode]

Summary

• API Client tool (/tools/api-client) — browser-based REST debugger, no vendor lock-in, no account required
• Imports Postman v2.1, Insomnia v4, OpenAPI 2/3 (JSON+YAML), and HAR files with auto-detection
• Exports back to Postman v2.1 + full workspace backup JSON
• Environment variables with {{var}} syntax; cross-request token chaining via VarSource (JSONPath from another request's saved response)
• Per-request response history ring (max 5, newest first); global history ring (max 50)
• Auto-save to localStorage — exact whiteboard countdown pattern (30s, amber chip, flush on visibility/pagehide/unload)
• Desktop: native HTTP via Tauri http_request command (reqwest, no CORS); Web: fetch() fallback with amber CORS warning banner
• Two-column layout with drag-resizable request/response split
• Bilingual SEO content (EN + ID)

Test plan

• npx vitest run — 915 tests, 0 failures
• npm run lint — 0 errors
• npm run build — completes, /tools/api-client/index.html present
• Import a Postman collection → requests appear in sidebar
• Import an OpenAPI YAML → requests generated from paths
• Send a GET request (web, CORS-friendly API like httpbin.org) → response shown
• Add env variable, reference with {{var}} in URL → substituted on send
• Edit request, wait 30s → amber chip counts down → auto-saves
• Click amber chip → saves immediately, chip → "✓ Saved"
• Reload page → workspace restored
• Export collection → valid Postman JSON downloaded
• Desktop app: send to any API → no CORS banner, full response
