feat(stats): added frustration metrics to stats parser and charting

- Added new frustration and revised behavior metrics across stats types, parser mappings, and UI charts.
- Reworked session sync to fan out parsing across a capped worker pool with SyncOptions progress callbacks.
- Added worker-based parse messaging and throttled TTY progress rendering in the stats sync command.
- Updated behavior scoring to strip structured content, ignore noisy prompts, and fix profanity boundary regressions.
- Expanded user message schema and migrations, then repaired assistant model/provider links during sync backfill.
- Updated worker-import guidance in AGENTS.md and recorded sync-progress/metrics updates in package changelogs.

 - **Class privacy**: use ES `#private` fields; leave externally accessible members bare. **No `private`/`protected`/`public` keyword on fields or methods**, except on **constructor parameter properties** where TypeScript requires it (e.g. `constructor(private readonly session: ToolSession)`).
 - **Promises**: use `Promise.withResolvers()` instead of `new Promise((resolve, reject) => ...)`.
 - **Prompts**: never build prompts in code (no inline strings, template literals, or concatenation). Prompts live in static `.md` files; use Handlebars for dynamic content. Import them via `import content from "./prompt.md" with { type: "text" }` — not `readFile`.
+- **Worker scripts**: reference the entry via `import workerUrl from "./worker.ts" with { type: "file" }` so the path survives bundling. tsgo flags it (TS1192/TS5097) — suppress with `// @ts-expect-error -- Bun file-URL import` directly above the line (see `tab-supervisor.ts`, `context-manager.ts`, `aggregator.ts`).
