feat(uniswap-integrations): migrate Slack MCP from addons generator to plugin

[cursor]

Add Slack MCP to the uniswap-integrations plugin, remove it from the addons generator, and ensure backward compatibility for existing Slack MCP configurations.

The claude-plus launcher now checks multiple config paths ($CLAUDE_CONFIG_DIR/claude.json, ~/.claude.json, ~/.claude/claude.json) to support users who previously installed Slack MCP via the addons generator (which used the legacy ~/.claude.json path) and those using the new plugin or default user config.

Summary

Migrate Slack MCP from the addons generator to the uniswap-integrations plugin, ensuring backward compatibility for users who previously installed Slack MCP via the legacy generator.

Changes

New: Slack MCP in uniswap-integrations Plugin

File	Changes
.mcp.json	Added Slack MCP server configuration with @anthropic/slack-mcp@latest
plugin.json	Bumped version 1.0.0 → 1.1.0
CLAUDE.md	Added Slack authentication documentation and setup instructions
README.md	Added Slack to MCP servers table and detailed setup guide

Removed: Slack MCP from Addons Generator

File	Changes
addon-registry.ts	Removed slack-mcp entry from registry
generator.ts	Removed Slack-specific authentication instructions
schema.json	Removed slack-mcp from enum options
schema.d.ts	Updated type to exclude slack-mcp
CLAUDE.md	Updated documentation to reflect removal

Backward Compatibility: Multi-Path Config Support

File	Changes
config-paths.ts	Added getAllClaudeConfigPaths() function for searching multiple config locations
slack-token.ts	Updated getCurrentToken() to search all config paths in priority order
The claude-plus launcher now searches these locations in order:

1. $CLAUDE_CONFIG_DIR/claude.json (if env var is set)
2. ~/.claude.json (legacy location from addons generator)
3. ~/.claude/claude.json (new default user location)

Notes

• Plugin version bumped from 1.0.0 → 1.1.0 (minor: new MCP server added)
• Users who installed Slack MCP via the addons generator will continue to work
• New installations should use the uniswap-integrations plugin
• The addons generator now only offers aws-log-analyzer-mcp

Test Plan

• Verify Slack MCP works when installed via uniswap-integrations plugin
• Verify claude-plus finds Slack token in ~/.claude.json (legacy path)
• Verify claude-plus finds Slack token in ~/.claude/claude.json (new path)
• Verify claude-plus finds Slack token when CLAUDE_CONFIG_DIR is set
• Verify addons generator no longer offers slack-mcp option
