fix(ton-trading-bot): add tests, fix lint warnings, register in README

[konard]

Summary

Fixes #39 — the TON Trading Bot plugin was installed but the agent couldn't discover or use it.

Root causes found and fixed

1. Plugin not listed in README — The agent's marketplace and documentation (README.md) did not include ton-trading-bot in the Available Plugins table. This is the primary reason the agent couldn't discover it via the web UI or docs. Fixed by adding it to the DeFi & Trading section and updating the badge counts (25→26 plugins, 183→189 tools).

2. No automated tests — The plugin had no tests/ folder, making it impossible to verify correctness automatically. Added 35 unit tests covering all 6 tools with a mocked SDK (no real network or disk access).

3. ESLint warnings — The context parameter was declared but unused in 5 of the 6 execute functions. Renamed to _context to match the project's no-unused-vars rule (only ton_trading_execute_swap uses context.chatId, so it keeps the original name).

What was verified as already correct

• manifest.json — all required fields present, id matches folder name, tools list matches index.js
• registry.json — plugin is correctly registered
• Plugin structure — manifest, migrate, and tools(sdk) exports are all valid
• sdk.storage, sdk.db, sdk.ton.dex usage — all follow the SDK pattern correctly

Tests added (plugins/ton-trading-bot/tests/index.test.js)

Suite	Tests
manifest	5
tools export + migrate	6
ton_trading_get_market_data	5
ton_trading_get_portfolio	3
ton_trading_validate_trade	6
ton_trading_simulate_trade	5
ton_trading_execute_swap	5
ton_trading_record_trade	5
Total	35

All 35 new tests pass. All 33 pre-existing ton-bridge tests continue to pass (68 total).

Test plan

• npm test — 68/68 tests pass
• node scripts/validate-plugins.mjs — ton-trading-bot: 6 tool(s) validated ✓
• eslint plugins/ton-trading-bot/**/*.js — 0 errors, 0 warnings
• Plugin appears in README DeFi & Trading table
