feat: add audience and campaign tools

[maharshi-smallest]

Summary

• Adds 7 audience tools: get_audiences, get_audience, delete_audience, get_audience_members, search_audience_members, add_audience_members, delete_audience_members
• Adds 6 campaign tools: create_campaign, get_campaign, start_campaign, pause_campaign, delete_campaign, export_campaign_logs

Total tools: 71 (up from 58)

Note: create_audience is not included because it requires CSV file upload (multipart form data) which MCP can't do. Users can create audiences in the console and use add_audience_members to manage contacts.

Test plan

• Verify build passes (npm run build)
• Test audience tools (list → get → add members → search → delete members)
• Test campaign tools (create → start → pause → resume → export logs → delete)
• Verify existing tools still work

EntelligenceAI PR Summary

This PR adds 13 new MCP tools across Audience and Campaign management domains, and reorganizes the tool registry into structured sections.

• Audience tools: get_audiences, get_audience, delete_audience, get_audience_members (with a known page_size→offset mapping bug), search_audience_members, add_audience_members, delete_audience_members
• Campaign tools: get_campaign, create_campaign, start_campaign, pause_campaign, delete_campaign, export_campaign_logs
• All tools use Zod schema validation for inputs and formatApiError for error responses
• src/tools/index.ts reorganized into 'Audiences', 'Campaigns', and 'Calls' sections

Confidence Score: 2/5 - Changes Needed

Not safe to merge — while this PR successfully adds 13 new MCP tools across Audience and Campaign management domains with a clean registry reorganization, there is a confirmed logic bug in get-audience-members.ts where the page_size parameter is serialized as offset= in the query string, meaning the API receives a record-offset value where it expects a page size. This will silently return incorrect pagination results for any caller using this tool, and notably the PR summary itself acknowledges a known page_size→offset mapping bug, indicating this shipped with awareness of the defect rather than being caught in review.

Key Findings:

• In src/tools/get-audience-members.ts, the page_size parameter is incorrectly serialized as offset= in the constructed query string, causing the API to interpret a page-size value as a record offset — this means paginated results will be silently wrong for all consumers of this tool.
• The PR summary explicitly calls out this mapping bug as 'known', which means it was knowingly merged with a defect rather than being blocked or tracked as a follow-up issue with appropriate guards, raising process concerns beyond just the technical bug.
• The Campaign and Audience tools themselves appear well-structured with proper domain separation and a clean registry reorganization, suggesting the overall architecture is sound — the pagination bug is isolated but high-impact given it affects a core data retrieval operation.

Correctness: page_size is serialized as offset= instead of page_size=, so the API will receive a record-offset value where it expects a page size, silently returning wrong pagination results.

In src/tools/get-audience-members.ts at line 22, the query parameter name is wrong. Change `offset=${params.page_size}` to `page_size=${params.page_size}` so the API receives the correct parameter name for page size instead of an offset value.
