## Strict TypeScript Convention Compliance

### `tsconfig.json`
- Added `strict: true` (umbrella flag covering `noImplicitAny`, `noImplicitThis`, `strictNullChecks`, `strictBindCallApply`, `strictFunctionTypes`, `strictPropertyInitialization`, `useUnknownInCatchVariables`, `alwaysStrict`).
- Added `exactOptionalPropertyTypes: true`.
- Added `noFallthroughCasesInSwitch: true`.
- Added `noPropertyAccessFromIndexSignature: true`.
- Added `forceConsistentCasingInFileNames: true`.
- Removed redundant individual flags superseded by `strict: true`.

### `src/main.ts`
- Changed `AIPulseSettings` to `import type` (type-only import).

### `src/ollama-client.ts`
- Replaced explicit `undefined` assignments on optional properties with conditional spread in `parseToolCalls()`.
- Replaced intermediate boolean guards with direct `!== undefined` narrowing in `chatAgentLoop()`.

### `src/chat-view.ts`
- Replaced `condition ? value : undefined` patterns with conditional spreads for `exactOptionalPropertyTypes` compliance in `handleSend()`.
- Removed 6 redundant `as HTMLDivElement` type assertions (already narrowed by null checks).
