test(init): add test coverage for init command (0%)

[agents-squads]

Problem

init.ts command has 0% test coverage — entire project initialization is untested.

Init is the first-run experience. Broken initialization causes:

• Project structure not created
• Missing files/directories
• Invalid config generation
• Silent failures

Location

• Source: src/commands/init.ts (680 lines)
• Test: MISSING

Coverage Analysis

• Current coverage: 0%
• Functions: prompt(), generate(), validate()
• Complete initialization pipeline untested

Regression Risk

MEDIUM: First-run experience. Broken init kills adoption.

Suggested Test Cases

• Create all required directories
• Generate valid SQUAD.md files
• Generate valid provider.yaml
• Handle existing project gracefully
• Validate user input
• Create BUSINESS_BRIEF.md
• Initialize memory structure
• Handle filesystem errors

Priority Rationale

P2: Critical for first-run but likely tested manually. Automate to catch regressions.
