feat: historical asset pricing tool

[premiumjibles]

Summary

• Adds getHistoricalPrices tool that fetches historical price data from CoinGecko's market_chart/range endpoint for one or more assets over a date range
• Accepts the same {assetId?, searchTerm?, network?} input pattern as getAssetPrices, plus startDate, endDate, and dataPoints (1-30, default 2)
• Returns evenly-spaced price points with computed startPrice, endPrice, and percentChange — enables questions like "what was ETH worth 2 months ago?" or "how much has BTC grown since January?"
• Uses partial success pattern: individual asset failures don't fail the batch

Test plan

• 7 unit tests for downsample utility (edge cases: empty, single element, boundary values)
• 17 tests for getHistoricalPrices tool (schema validation, happy path, partial failure, API errors, empty data, parallel fetching, single data point)
• Full test suite: 231/231 passing, 0 regressions
• TypeScript type-check clean
• Manual test: ask the agent "what was ETH worth 2 months ago?" and verify it uses getHistoricalPrices

📝 Walkthrough

Walkthrough

The PR adds a new getHistoricalPrices tool (schema, execution, CoinGecko range API integration, downsampling, results/errors), exports the new tool, introduces asset-resolution helpers and CoinGecko types, adds tests, removes numerous debug logs across many tools, tweaks two UI components, and adds three bug-report tickets.

Changes

Cohort / File(s)	Summary
Historical Pricing Tool apps/agentic-server/src/tools/getHistoricalPrices.ts, apps/agentic-server/src/tools/__tests__/getHistoricalPrices.test.ts	New tool with Zod schema, asset resolution, CoinGecko market_chart/range fetches, downsampling, per-asset result/error aggregation, and comprehensive tests.
CoinGecko API & Types apps/agentic-server/src/lib/asset/coingecko/types.ts, apps/agentic-server/src/lib/asset/coingecko/api.ts, apps/agentic-server/src/lib/asset/coingecko/index.ts	Added MarketChartRangeResponse type, implemented getMarketChartRange() and re-exported them.
Downsampling & Asset Resolve apps/agentic-server/src/lib/asset/coingecko/downsample.ts, apps/agentic-server/src/lib/asset/coingecko/__tests__/downsample.test.ts, apps/agentic-server/src/lib/asset/resolveAsset.ts	New downsample utility with tests; new helpers searchAsset and getAssetMeta to resolve assets/metadata and re-export CoinGecko mapping helper.
Tool Registration & Exports apps/agentic-server/src/routes/chat.ts, apps/agentic-server/src/index.ts	Registered getHistoricalPricesTool in tools and exported the tool/execute/types from server index. Minor route UI mapping update.

Poem

🐰 Hoppity hops, the charts now sing,

Coins through time in an even ring,
Logs trimmed tidy, tests in flight,
Downsampled days and markets bright,
A rabbit cheers: data done right!
