Trigix v1.1.0

New AI-native and enterprise capabilities, a custom node SDK, and a major
quality/CI uplift. Backward compatible with 1.0.0.

Added

AI-native

• RAG knowledge store on pgvector in the AI runti
  e: ingest, embed (OpenAI or
  an offline local embedding), and cosine-similarity retrieval.
• rag and rag_ingest workflow nodes, plus a Knowledge Bases management page.
• Agent tool-use loop: the Agent node can call tools (sandboxed calculator and
  knowledge-base search) and iterate to an answer.

Custom node SDK (node ecosystem)

• Python (trigix-node-sdk on PyPI) and TypeScript/JavaScript
  (trigix-node-sdk on npm) SDKs for writing nodes served over HTTP.
• custom node type, a tenant-scoped node registry, and one-click registration
  from a node service's /manifest.
• Example nodes (HTML to text, PII redaction, sentiment) and an end-to-end demo.

Enterprise

• Enterprise SSO via OIDC (Okta / Azure AD / Google Workspace / Alibaba Cloud
  IDaaS / Huawei OneAccess / Tencent / Authing) plus Feishu, DingTalk, and
  WeChat Work; admin management UI with enable/disable.
• Encryption at rest for credential and SSO secrets (AES-256-GCM via
  CREDENTIAL_MASTER_KEY), with transparent passthrough of legacy plaintext.
• Dead-letter queue for the Redis Streams execution queue; failed jobs are
  preserved and can be re-driven instead of silently dropped.
• Opt-in data retention sweeper (DATA_RETENTION_DAYS) for executions, audit
  log, token usage, and webhook deliveries.

Changed

• Split the 14k-line executor.rs (previously include!-spliced) into cohesive
  submodules.
• CI now enforces formatting, the full Rust test suite, the web production
  build, the AI runtime tests against a pgvector service, and both node SDK test
  suites.

Fixed

• Repaired a test suite that did not compile and 122 frontend TypeScript build
  errors.
• Credential creation on PostgreSQL (an i64 was bound to a TIMESTAMPTZ column).
• A few latent frontend bugs surfaced by the typechecker.
