feat: complete custom agent support for ALL remaining IDEs

## Added installCustomAgentLauncher to remaining IDEs:

✅ Qwen (.qwen/commands/BMad/)
- TOML format with proper description and prompt fields
- Uses existing processAgentLauncherContent method
- Format: custom-{agent-name}.toml

✅ Trae (.trae/rules/)
- Markdown format with bmad-agent-custom- prefix
- Follows existing BMAD naming pattern
- Format: bmad-agent-custom-{agent-name}.md

✅ Roo (.roomodes)
- YAML format appends to existing customModes section
- Creates customModes section if missing
- Format: bmad-custom-{agent-name} (slug-based)

✅ Kilo (.kilocodemodes)
- YAML format identical to Roo pattern
- Handles existing customModes gracefully
- Format: bmad-custom-{agent-name} (slug-based)

✅ Auggie (.augment/commands/bmad/)
- Frontmatter + Markdown format
- Follows existing Auggie command pattern
- Format: custom-{agent-name}.md

## Complete IDE Coverage:
ALL IDEs now support custom agent installation:
- 16 total IDEs with custom agent support
- Various formats: TOML, YAML, Markdown, file-based
- All include @agentPath references and usage instructions
- Proper IDE-specific naming and directory structures

Custom agents from .bmad/custom/src/agents/ now install to EVERY configured IDE!
