Add two new MCP tools for channel membership management:
- conversations_join: Join public channels via conversations.join API.
Idempotent — joining a channel you're already in is a no-op.
Requires channels:join (xoxb) or channels:write (xoxp) scope.
- conversations_leave: Leave channels, group conversations, or DMs
via conversations.leave API. Marked as destructive.
Requires channels:manage (xoxb) or channels:write (xoxp) scope.
On Enterprise Grid with session tokens (xoxc/xoxd), routes through
the edge API to bypass enterprise_is_restricted errors.
Both tools accept channel IDs (Cxxxxxxxxxx) or names (#channel-name)
using the existing resolveChannelID helper.
Updated docs/01-authentication-setup.md with new OAuth scopes
(channels:join, channels:manage) and docs/03-configuration-and-usage.md
with the new tool names in the available tools list.
- Add support for bot tokens as an alternative authentication method
- Conditionally register search tool only for non-bot tokens (bots cannot use search.messages API)
- Update isOAuth definition to include both xoxp and xoxb tokens for cleaner implementation
- Add bot token configuration to manifest-dxt.json for DXT extension
- Document bot token limitations in README and authentication setup guide
