Trigix v1.3.0

A large expansion of the workflow node catalog — 44 new node types
(136 → 180) — covering the gaps against comparable workflow/automation
tools and deepening the AI-native and Chinese-enterprise coverage. Each node
is full-stack (engine + config UI) and backward compatible. Most are plain
HTTP; the few that aren't were deliberately implemented in pure Rust (or via a
runtime CLI) so the default cargo build needs no extra system library.

Added

LLM providers

• azure_openai (deployment-based, api-key header), vertex (Google Vertex
  AI / Gemini generateContent with a caller-supplied OAuth2 token), bedrock
  (AWS Bedrock InvokeModel, model-native body), grok (xAI), and ollama
  (self-hosted, OpenAI-compatible).

AI-native building blocks (OpenAI-/Cohere-compatible, configurable base URL)

• embedding, reranker, text_splitter (pure-compute, UTF-8-safe chunking),
  structured_output (LLM JSON mode), classifier, image_gen,
  speech_to_text (Whisper, multipart upload), and tts.

Vector stores

• weaviate (REST + GraphQL), chroma (REST data API), and milvus / Zilliz
  (REST API v2).

Databases & data warehouses

• mongodb (Atlas Data API), clickhouse (HTTP), mysql (sqlx), snowflake
  (SQL API v2, bearer token), bigquery (jobs.query REST), and sqlserver
  (Microsoft SQL Server over the pure-Rust tiberius TDS driver — no native
  client needed).

Object storage

• gcs (Google Cloud Storage JSON API) and azure_blob (REST + SAS token),
  both using caller-supplied credentials.

AWS (a from-scratch Signature V4 signer — no AWS SDK — validated against
AWS's published get-vanilla test vector)

• sqs, sns, and bedrock.

Message brokers

• kafka (Confluent REST Proxy) and rabbitmq (Management HTTP API).

Chinese enterprise collaboration

• feishu / Lark (custom-bot webhook or app message API), dingtalk (custom
  robot with optional HMAC sign), and wecom (WeChat Work group robot).

Network file / shell / mail (pure-Rust clients — no libssh2/system library)

• ftp / FTPS (suppaftp), sftp and ssh (russh / russh-sftp, password or
  private-key auth), and imap (TLS mailbox reads).

Utilities & core primitives

• hash (SHA-256/384/512 + HMAC), jwt (HS256/384/512 sign & verify),
  zip (create/extract), image (resize/convert/metadata), pdf_extract
  (text extraction), ocr (via the tesseract CLI), html_extract (CSS
  selectors), rss (RSS/Atom/JSON feeds), and wait (pause for a duration /
  until a timestamp, or suspend until externally resumed via the existing
  approve/resume endpoint).

Notes

• The ocr node needs the tesseract CLI on the executor host; all other
  nodes have no extra runtime dependency.
• The wait (resume mode) and snowflake/bigquery/vertex/gcs/azure_blob
  nodes take a caller-supplied token rather than performing their own
  credential exchange.
