chore: initialize repository baseline

Import the existing Electron + React + TypeScript app as the version-control
baseline before the scanner rework (C# input/capture sidecar, resolution-anchored
layout profiles, OCR preprocessing, eval harness, rescan-merge, GOOD interop).

Housekeeping in this commit:
- Remove orphaned temp_inputhelper_block.ts (duplicate of the input-helper script).
- Ignore .claude/scheduled_tasks.lock local session state.
- Add .gitattributes to normalize line endings (LF in repo).

+# Development Workflow
+
+## 1. Clarify Scope
+
+Define whether the task affects scanner capture, OCR parsing, recommendations, UI, documentation, or packaging. Scanner and automation work require extra safety review.
+
+## 2. Inspect Existing Code
+
+Use `rg` and read the relevant files before editing. For this project, likely starting points are:
+
+- `electron/main.ts`
+- `electron/preload.cjs`
+- `src/App.tsx`
+- `src/lib/artifactOcrParser.ts`
+- `src/lib/scoring.ts`
+- `src/styles/global.css`
+
+## 3. Implement Small Changes
+
+Keep edits focused. Avoid mixing UI redesign, scanner logic, parser logic, and documentation unless the request explicitly spans them.
+
+## 4. Validate
+
+Default validation:
+
+```powershell
+npm run lint
+npm test
+npm run build
+```
+
+For scanner changes, restart Electron after build or after changing `electron/main.ts`, because the main process does not hot reload reliably.
+
+## 5. Manual Smoke Test
+
+For Smart Capture:
+
+1. Open Genshin in borderless/windowed mode.
+2. Open the artifact inventory detail view.
+3. Click `Sources` and confirm Genshin is selected or available.
+4. Click `Smart Capture`.
+5. Confirm the preview shows the artifact detail panel.
+6. Open `Details` and inspect crops/OCR.
+
+## 6. Review Outcome
+
+Document important scanner heuristics, accepted limitations, and future fixes in `docs/DECISIONS.md` or this workflow when they become durable.
