feat(demo): Stage 2 PR-4 — secondary fixture richness

[luokerenx4]

Summary

Final Stage 2 PR. Fills the long tail of fixture content so the demo doesn't look gutted once a visitor scrolls past the Inbox / workspace / transcript flagship flow from PR-3.

Stacks on top of PR #221, PR #222, PR #223.

What changed

3 trading accounts (instead of 1)

UTA	Provider	NL	Positions
Alpaca Paper	alpaca	$52,840	AAPL · NVDA · GOOG · AMD (stocks)
IBKR Demo	ibkr	$247,310	SPY · QQQ · TLT · AAPL options (mix incl. underwater P&L)
Binance Spot	ccxt	$15,032 USDT	BTC · ETH (spot)

Per-UTA AccountInfo, Position[], and snapshot summaries served from the trading handler. The equity curve generator uses a seeded random walk (per-UTA distinct vol + drift) so the Portfolio chart shows plausibly-trending lines that stay consistent across page reloads — visitors who refresh see the same state.

6 news articles

Reuters / Bloomberg / CNBC / WSJ / CoinDesk spread across the last 22 hours covering AAPL Q1, NVDA capex, Fed minutes, BTC, SPY, TLT. The AAPL article (30m ago) ties to the Inbox AAPL research from PR-3 (5m ago) — completes the narrative "news landed → agent dug in → wrote up the deceleration signal".

4 cron jobs

• Morning market prep — weekdays 8:30 AM, enabled
• EOD snapshot + journal — weekdays 4:05 PM, enabled
• Weekly position review — Fridays 5 PM, disabled (shows the toggle state)
• AAPL watch alert — every 15m, enabled (ties to AAPL narrative)

Mix of cron-syntax vs every-N-minutes; mix of enabled/disabled to exercise the UI states.

Skipped (intentional)

• Topology graph fake — Dev page only, low marketing value
• Populated agent-status log — PR-3's events SSE already carries the "system is alive" signal at the more visible surface

Verification

Check	Result
pnpm -F open-alice-ui exec tsc -b	clean
pnpm -F open-alice-ui build (prod)	zero fixture leak in main chunk (Alpaca Paper, Binance Spot, Morning market prep, demoCronJobs, demoNewsArticles — all absent)
pnpm dev:demo + Playwright	portfolio chart renders the random-walk equity curve + cumulative equity numbers ($315,182.71 total across 3 UTAs); news page lists all 6 articles with source badges + category labels

Stage 2 wrap-up

This PR closes Stage 2. With #221 → #222 → #223 → #224 merged:

• Vercel-deployable static-mode bundle
• PTY transcript replay + browser-side recorder for capturing real sessions
• Coherent flagship scenario (Inbox AAPL report ↔ workspace session ↔ live markdown render)
• Rich secondary fixtures (3 UTAs / equity curves / news / cron)

What's NOT in Stage 2 (could become Stage 3 if marketing-grade demo is the goal):

• Real recorded transcript replacing the hand-crafted AAPL one — needs user to run the recorder tool on a live session
• In-memory mutation persistence (creating a cron job in demo mode, having it appear in the list)
• Persistent dismissable "Demo Mode" banner with deep links to specific scenarios
• Multiple workspace transcripts the visitor can pick between

Test plan

• tsc -b clean
• Prod build: no fixture string leaks in main chunk
• Demo build still produces valid bundle
• Portfolio shows multi-UTA chart + totals
• News page lists 6 articles with metadata
• Manual: visitor flow on Vercel preview — start at /inbox, click report, jump to workspace, watch terminal replay (deferred to user after deploy)

Boundary touch

None — no trading / auth / broker / migrations code modified.
