Shaun Arman 8839075805 feat: initial implementation of TFTSR IT Triage & RCA application
Implements Phases 1-8 of the TFTSR implementation plan.

Rust backend (Tauri 2.x, src-tauri/):
- Multi-provider AI: OpenAI-compatible, Anthropic, Gemini, Mistral, Ollama
- PII detection engine: 11 regex patterns with overlap resolution
- SQLCipher AES-256 encrypted database with 10 versioned migrations
- 28 Tauri IPC commands for triage, analysis, document, and system ops
- Ollama: hardware probe, model recommendations, pull/delete with events
- RCA and blameless post-mortem Markdown document generators
- PDF export via printpdf
- Audit log: SHA-256 hash of every external data send
- Integration stubs for Confluence, ServiceNow, Azure DevOps (v0.2)

Frontend (React 18 + TypeScript + Vite, src/):
- 9 pages: full triage workflow NewIssue→LogUpload→Triage→Resolution→RCA→Postmortem→History+Settings
- 7 components: ChatWindow, TriageProgress, PiiDiffViewer, DocEditor, HardwareReport, ModelSelector, UI primitives
- 3 Zustand stores: session, settings (persisted), history
- Type-safe tauriCommands.ts matching Rust backend types exactly
- 8 IT domain system prompts (Linux, Windows, Network, K8s, DB, Virt, HW, Obs)

DevOps:
- .woodpecker/test.yml: rustfmt, clippy, cargo test, tsc, vitest on every push
- .woodpecker/release.yml: linux/amd64 + linux/arm64 builds, Gogs release upload

Verified:
- cargo check: zero errors
- tsc --noEmit: zero errors
- vitest run: 13/13 unit tests passing

# buffer-crc32
[![NPM Version](https://img.shields.io/npm/v/buffer-crc32.svg)](https://npmjs.org/package/buffer-crc32)
[![Build Status](https://github.com/brianloveswords/buffer-crc32/actions/workflows/ci.yml/badge.svg)](https://github.com/brianloveswords/buffer-crc32/actions/workflows/ci.yml)
crc32 that works with binary data and fancy character sets, outputs
buffer, signed or unsigned data and has tests.
Derived from the sample CRC implementation in the PNG specification: http://www.w3.org/TR/PNG/#D-CRCAppendix
This package requires Node 8+ to work.
# install
```
npm install buffer-crc32
```
# example
```js
const crc32 = require('buffer-crc32');
// works with buffers
const buf = Buffer([0x00, 0x73, 0x75, 0x70, 0x20, 0x62, 0x72, 0x6f, 0x00]);
crc32(buf); // -> <Buffer 94 5a ab 4a>
// has convenience methods for getting signed or unsigned ints
crc32.signed(buf); // -> -1805997238
crc32.unsigned(buf); // -> 2488970058
// will cast to buffer if given a string, so you can
// directly use foreign characters safely
crc32('自動販売機'); // -> <Buffer cb 03 1a c5>
// and works in append mode too
const partialCrc = crc32('hey');
const partialCrc = crc32(' ', partialCrc);
const partialCrc = crc32('sup', partialCrc);
const partialCrc = crc32(' ', partialCrc);
const finalCrc = crc32('bros', partialCrc); // -> <Buffer 47 fa 55 70>
```
# tests
This was tested against the output of zlib's crc32 method. You can run
the tests with`npm test` (requires tap)
# see also
https://github.com/alexgorbatchev/node-crc, `crc.buffer.crc32` also
supports buffer inputs and return unsigned ints (thanks @tjholowaychuk).
