fix: resolve spawn npm ENOENT errors for composio-direct and stormtrade

[konard]

Summary

Fixes #125 — Three plugin loader errors reported on Windows.

Root causes and fixes

1. [composio-direct] Failed to install deps: Error: spawn npm ENOENT

Root cause: PR #120 added package.json and package-lock.json to the composio-direct plugin to auto-install @composio/core at startup. The Teleton PluginLoader spawns npm ci as a child process, but on Windows npm is only available as npm.cmd. Using spawn('npm') fails with ENOENT because the executable is not found.

Fix: Remove package.json and package-lock.json. The @composio/core SDK is already lazy-loaded via dynamic import() with graceful fallback to direct HTTP API calls (added in PR #120). No npm install is needed at startup — the plugin works fully without the SDK.

2. [stormtrade] Failed to install deps: Error: spawn npm ENOENT + Cannot find module '@storm-trade/sdk'

Root cause: Same Windows npm ENOENT issue. Additionally, @storm-trade/sdk was require()d at the top level (not lazily), so when npm install fails and the module is missing, the entire plugin fails to import.

Fix: Remove package.json and package-lock.json, and make @storm-trade/sdk import lazy using try/catch — the same pattern used in tonco-dex (PR #92).

To install the optional SDK for full write functionality:

cd ~/.teleton/plugins/stormtrade && npm install

3. [ton-trading-bot] invalid manifest: description too long (>256 chars)

Already fixed in commit 4a1e053 (description truncated from 269 → 221 chars, which is within the 256-character limit). No additional changes needed.

Test plan

• node scripts/validate-plugins.mjs — all 3 affected plugins validate: [OK] composio-direct: 4 tool(s), [OK] stormtrade: 13 tool(s), [OK] ton-trading-bot: 24 tool(s)
• node scripts/run-tests.mjs — all 234 tests pass
• npx eslint plugins/composio-direct/index.js plugins/stormtrade/index.js — no new errors (pre-existing warnings only)
