Add ticker-bar extension

[kays0x]

Description

Ticker Bar keeps a mixed market watchlist in the macOS menu bar. It supports stocks, crypto, Binance spot pairs and perpetual futures, on-chain tokens, and Polymarket outcomes without requiring an account or API key.

Highlights

• Show the primary ticker, optional daily change, and optional provider artwork in the menu bar.
• Search and manage assets across Yahoo Finance, CoinGecko, Binance, DexScreener, and Polymarket.
• Inspect quote details including daily range, volume, market cap, funding, market state, provider, and freshness when available.
• Render cached quotes immediately and preserve the last valid value when a provider is unavailable.
• Batch requests, enforce timeouts, and apply provider-specific cache and rate-limit cooldowns.
• Bulk edit and validate exact market identifiers for advanced watchlists.

Screenshot

The Store metadata contains three screenshots covering Browse Markets, Manage Watchlist, and the advanced editor. The README also shows the menu-bar dropdown.

Verification

• 22 automated tests pass, including refresh-lease and cache-reconciliation coverage.
• npm run lint passes.
• npm run build passes.
• All five commands were tested in Raycast on macOS.

Checklist

• I read the extension guidelines
• I read the documentation about publishing
• I ran npm run build and tested this distribution build in Raycast
• I checked that files in the assets folder are used by the extension itself
• I checked that assets used by the README are placed outside of the metadata folder

Greptile Summary

Adds the Ticker Bar Raycast extension.

• Provides menu-bar quotes and watchlist management for stocks, crypto, Binance markets, DEX tokens, and Polymarket outcomes.
• Adds provider adapters, batching, caching, refresh leases, local persistence, market search, quote details, tests, documentation, and Store metadata.
• Updates the previously flagged changelog placeholder and generated preference typing.

Confidence Score: 4/5

The PR is not yet safe to merge because removed assets can be restored by in-flight refreshes and the storage lease still permits overlapping protected operations.

Explicit-ID refreshes bypass the current-watchlist guard, while the process-local lock only wraps non-atomic LocalStorage lease operations; concurrent commands can consequently restore removed cache entries or overwrite newer market state.

Files Needing Attention: extensions/ticker-bar/src/market-refresh.ts, extensions/ticker-bar/src/storage-lock.ts

Important Files Changed

Filename	Overview
extensions/ticker-bar/src/market-refresh.ts	Adds cache-first provider refresh and reconciliation, but explicit-ID refreshes still permit removed assets to be restored.
extensions/ticker-bar/src/storage-lock.ts	Adds heartbeat renewal and cleanup, but cross-command acquisition and cleanup remain non-atomic.
extensions/ticker-bar/src/market-storage.ts	Implements normalized watchlist and quote persistence while removing the previously flagged manual preference declaration.
extensions/ticker-bar/CHANGELOG.md	Adds the initial release entry using the required merge-date placeholder.
