fix: ANTHROPIC_API_KEY no longer overrides --provider argument (#60)

Critical bug fix for provider selection:

- CLI arguments (--provider, --openrouter-key, etc.) now properly propagate to environment variables
- Removed silent fallback to ANTHROPIC_API_KEY for non-Anthropic providers
- Added validation requiring provider-specific API keys with clear error messages
- CLI arguments correctly override environment variables as expected

Breaking Change:
- Providers now require their specific API keys (no fallback to ANTHROPIC_API_KEY)
- OpenRouter requires OPENROUTER_API_KEY or --openrouter-key
- Gemini requires GOOGLE_GEMINI_API_KEY
- Requesty requires REQUESTY_API_KEY

Files changed:
- src/index.ts: Propagate CLI options to environment variables
- src/agents/claudeAgent.ts: Remove ANTHROPIC_API_KEY fallback, add validation
- tests/validation/test-provider-cli-args.ts: Comprehensive test suite
- package.json: Version bump to 1.10.1
- CHANGELOG.md: Document changes and migration guide

Fixes #60
