Nicolas Cantu cfa1f435cb refactor: centralize HTTP proxy helpers and align IA_DEV_ROOT resolution (0.0.6) 
Initial state:
- HTTP proxy utilities (Bearer parsing, hop-by-hop headers, body limits, safe path validation) were duplicated between smart-ide-sso-gateway and smart-ide-global-api.
- IA_DEV_ROOT auto-resolution order differed between bash (ensure-ia-dev-project-link.sh) and TypeScript (ia-dev-gateway getIaDevRoot), and could fall back to non-existing paths.

Motivation:
- Reduce duplication and drift across proxy layers.
- Enforce consistent, explicit IA_DEV_ROOT behavior across scripts and services.

Resolution:
- Add package @4nk/smart-ide-http-utils and reuse it from smart-ide-sso-gateway and smart-ide-global-api.
- Align IA_DEV_ROOT resolution to prefer ./services/ia_dev then ./ia_dev; fail fast when missing/misconfigured.

Root cause:
- Cross-service utilities were implemented ad-hoc in each service.
- Historical layout transitions (ia_dev gitlink vs vendored services/ia_dev) left multiple resolvers with different priorities.

Impacted features:
- HTTP proxy chain (SSO gateway -> global API -> upstream services).
- ia-dev-gateway startup/operation when IA_DEV_ROOT is missing or invalid.

@4nk/smart-ide-http-utils

Utilitaires HTTP partagés pour les services Node/TypeScript du monorepo smart_ide.

Objectifs :

  • Réduire la duplication (Bearer, limites de body, headers hop-by-hop, etc.).
  • Centraliser les garde-fous de proxy (ex. rejet des segments .. dans les chemins relayés).

Fonctions exposées :

  • readBearer(req) : lit Authorization: Bearer ….
  • readBodyBuffer(req, maxBytes) : lit un corps en mémoire avec plafond explicite.
  • copyHeadersForProxy(req) : copie les headers d’entrée en excluant hop-by-hop + Authorization.
  • isSafeProxyPath(path) : valide un chemin relayé (refuse . / .. même encodés).
  • REQUEST_HOP_BY_HOP_HEADERS, RESPONSE_HOP_BY_HOP_HEADERS.

Build

Le répertoire dist/ est versionné pour que les services puissent installer ce paquet via file: sans étape de build préalable.

Après modification de src/ :

cd packages/smart-ide-http-utils
npm ci && npm run build
