feat: Add ide-only and web-only menu item filtering for platform-specific commands

## Summary
- Add ide-only and web-only boolean fields to agent menu schema
- Filter menu items based on build target (web bundle vs local IDE)
- Update BMM agent definitions with platform restrictions and improved descriptions
- Update frame-expert agent icon to 📐 and add webskip flag

## Changes

### Schema & Bundler Updates
- tools/schema/agent.js: Add ide-only and web-only optional boolean fields
- tools/cli/lib/yaml-xml-builder.js: Filter ide-only items from web bundles
- tools/cli/lib/xml-handler.js: Pass forWebBundle flag through build chain

### Agent Updates
- frame-expert: Change icon to 📐, add webskip flag, improve principle formatting
- pm: Mark workflow-init and correct-course as ide-only, advanced-elicitation as web-only
- ux-designer: Rename trigger to create-ux-design, mark advanced-elicitation as web-only
- sm: Rename triggers for consistency (story-context → create-story-context)
- analyst: Add research workflow after brainstorm, mark advanced-elicitation as web-only
- architect: Remove document field from validate-architecture, add web-only flag
- dev: Update persona and critical actions for clarity
- tech-writer: Add party-mode workflow, mark advanced-elicitation as web-only
- tea: Mark advanced-elicitation as web-only
- All agents: Standardize party-mode description

This enables platform-specific functionality where some commands only make sense
in IDE environments (workflow-init) or web interfaces (advanced-elicitation).
