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).

+# Release Process
+
+## Local Release Readiness
+
+Before packaging:
+
+1. Run `npm run lint`.
+2. Run `npm test`.
+3. Run `npm run build`.
+4. Start the Electron app.
+5. Run a manual Smart Capture smoke test.
+
+## Packaging
+
+The package configuration lives in `package.json` under `build`.
+
+Future packaging command:
+
+```powershell
+npx electron-builder --win
+```
+
+## Rollback
+
+Until releases are formalized, rollback means returning to the last known working project folder or Git commit. Do not overwrite user data or local snapshots during rollback.
