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

/**
* Access the file system.
*
* ## Security
*
* This module prevents path traversal, not allowing parent directory accessors to be used
* (i.e. "/usr/path/to/../file" or "../path/to/file" paths are not allowed).
* Paths accessed with this API must be either relative to one of the {@link BaseDirectory | base directories}
* or created with the {@link https://v2.tauri.app/reference/javascript/api/namespacepath/ | path API}.
*
* The API has a scope configuration that forces you to restrict the paths that can be accessed using glob patterns.
*
* The scope configuration is an array of glob patterns describing file/directory paths that are allowed.
* For instance, this scope configuration allows **all** enabled `fs` APIs to (only) access files in the
* *databases* directory of the {@link https://v2.tauri.app/reference/javascript/api/namespacepath/#appdatadir | `$APPDATA` directory}:
* ```json
* {
* "permissions": [
* {
* "identifier": "fs:scope",
* "allow": [{ "path": "$APPDATA/databases/*" }]
* }
* ]
* }
* ```
*
* Scopes can also be applied to specific `fs` APIs by using the API's identifier instead of `fs:scope`:
* ```json
* {
* "permissions": [
* {
* "identifier": "fs:allow-exists",
* "allow": [{ "path": "$APPDATA/databases/*" }]
* }
* ]
* }
* ```
*
* Notice the use of the `$APPDATA` variable. The value is injected at runtime, resolving to the {@link https://v2.tauri.app/reference/javascript/api/namespacepath/#appdatadir | app data directory}.
*
* The available variables are:
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#appconfigdir | $APPCONFIG},
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#appdatadir | $APPDATA},
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#applocaldatadir | $APPLOCALDATA},
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#appcachedir | $APPCACHE},
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#applogdir | $APPLOG},
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#audiodir | $AUDIO},
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#cachedir | $CACHE},
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#configdir | $CONFIG},
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#datadir | $DATA},
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#localdatadir | $LOCALDATA},
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#desktopdir | $DESKTOP},
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#documentdir | $DOCUMENT},
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#downloaddir | $DOWNLOAD},
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#executabledir | $EXE},
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#fontdir | $FONT},
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#homedir | $HOME},
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#picturedir | $PICTURE},
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#publicdir | $PUBLIC},
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#runtimedir | $RUNTIME},
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#templatedir | $TEMPLATE},
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#videodir | $VIDEO},
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#resourcedir | $RESOURCE},
* {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#tempdir | $TEMP}.
*
* Trying to execute any API with a URL not configured on the scope results in a promise rejection due to denied access.
