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

## What is this?
This is a tiny package that finds the count of the longest adjacent repeating
substring.
## When should I use this?
This package is rather niche.
I use it for serializing markdown ASTs (particularly fenced code and math).
You can use [`ccount`][ccount] if you need the total count of substrings
occuring in a value.
## Install
This package is [ESM only][esm].
In Node.js (version 14.14+, 16.0+), install with [npm][]:
```sh
npm install longest-streak
```
In Deno with [`esm.sh`][esmsh]:
```js
import {longestStreak} from 'https://esm.sh/longest-streak@3'
```
In browsers with [`esm.sh`][esmsh]:
```html
<script type="module">
import {longestStreak} from 'https://esm.sh/longest-streak@3?bundle'
</script>
```
## Use
```js
import {longestStreak} from 'longest-streak'
longestStreak('` foo `` bar `', '`') // => 2
```
## API
This package exports the identifier `longestStreak`.
There is no default export.
### `longestStreak(value, substring)`
Get the count of the longest repeating streak of `substring` in `value`.
###### Parameters
* `value` (`string`) — content to search in
* `substring` (`string`) — substring to look for, typically one character
###### Returns
Count of most frequent adjacent `substring`s in `value` (`number`).
## Types
This package is fully typed with [TypeScript][].
It exports no additional types.
## Compatibility
This package is at least compatible with all maintained versions of Node.js.
As of now, that is Node.js 14.14+ and 16.0+.
It also works in Deno and modern browsers.
## Security
This package is safe.
## Related
* [`wooorm/ccount`](https://github.com/wooorm/ccount)
— count the total number of `substring`s in `value`
* [`wooorm/direction`](https://github.com/wooorm/direction)
— detect directionality: left-to-right, right-to-left, or neutral
