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

# @emotion/cache
### createCache
`createCache` allows for low level customization of how styles get inserted by emotion. It's intended to be used with the [`<CacheProvider/>`](https://emotion.sh/docs/cache-provider) component to override the default cache, which is created with sensible defaults for most applications.
```javascript
import createCache from '@emotion/cache'
export const myCache = createCache({
key: 'my-prefix-key',
stylisPlugins: [
/* your plugins here */
]
})
```
### Primary use cases
- Using emotion in embedded contexts such as an `<iframe/>`
- Setting a [nonce](#nonce-string) on any `<style/>` tag emotion creates for security purposes
- Using emotion with a developer defined `<style/>` tag
- Using emotion with custom Stylis plugins
## Options
### `nonce`
`string`
A nonce that will be set on each style tag that emotion inserts for [Content Security Policies](https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP).
### `stylisPlugins`
`Array<Function>`
A Stylis plugins that will be run by Stylis during preprocessing. [Read the Stylis docs to find out more](https://github.com/thysultan/stylis.js#middleware). This can be used for many purposes such as RTL.
> Note:
>
> Prefixer is just a plugin which happens to be put in default `stylisPlugins`. If you plan to use custom `stylisPlugins` and you want to have your styles prefixed automatically you must include prefixer in your custom `stylisPlugins`. You can import `prefixer` from the `stylis` module to do that (`import { prefixer } from 'stylis'`);
### `key`
`string (Pattern: [^a-z-])`
The prefix before class names. It will also be set as the value of the `data-emotion` attribute on the style tags that emotion inserts and it's used in the attribute name that marks style elements in `renderStylesToString` and `renderStylesToNodeStream`. This is **required if using multiple emotion caches in the same app**.
### `container`
`Node`
A DOM node that emotion will insert all of its style tags into. This is useful for inserting styles into iframes or windows.
### `prepend`
`boolean`
A boolean representing whether to prepend rather than append style tags into the specified container DOM node.
