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).

+# Checklists
+
+## Scanner Change
+
+- [ ] The expected crop or capture behavior is clear.
+- [ ] Genshin is not accessed through memory reads, hooks, injection, or game files.
+- [ ] Capture failures are shown to the user.
+- [ ] OCR uncertainty remains inspectable in Details.
+- [ ] Parser output does not silently trust low-confidence text.
+- [ ] `npm run lint` passes.
+- [ ] `npm test` passes when parser/scoring logic changed.
+- [ ] `npm run build` passes.
+- [ ] Manual Smart Capture is tested when possible.
+
+## UI Change
+
+- [ ] The main workflow remains visible without unnecessary scrolling.
+- [ ] Debug or secondary information is moved behind buttons/modals where appropriate.
+- [ ] Disabled states prevent actions without required data.
+- [ ] Text fits in controls and panels.
+- [ ] Desktop viewport is checked manually.
+- [ ] `npm run build` passes.
+
+## Parser Or Scoring Change
+
+- [ ] Known-good OCR samples still parse correctly.
+- [ ] Ambiguous data becomes unknown or review, not false certainty.
+- [ ] Character, set, stat, and slot dictionaries are updated deliberately.
+- [ ] Tests cover changed behavior when practical.
+
+## Release Or Packaging
+
+- [ ] Production build succeeds.
+- [ ] Electron preload bridge is copied to `dist-electron/preload.cjs`.
+- [ ] App starts outside browser preview.
+- [ ] Smart Capture bridge is available.
+- [ ] No generated debug artifacts are included accidentally.
