chore: bump chart to 0.2.0

[thepagent]

0.2.0 — Codex & Claude Code Support

New Features

• Codex backend — Use OpenAI Codex via @zed-industries/codex-acp adapter
• Claude Code backend — Use Anthropic Claude Code via @agentclientprotocol/claude-agent-acp adapter
• agent.preset — One-line backend selection: --set agent.preset=codex or --set agent.preset=claude
• Separate Docker images — agent-broker-codex and agent-broker-claude published to GHCR alongside the default agent-broker (kiro-cli)
• Dynamic NOTES.txt — Auth instructions adapt to the selected backend

Breaking Changes

• PVC mount changed — Now mounts entire /home/agent instead of individual subPaths (dot-kiro, kiro-cli-data). Existing kiro-cli users may need to re-authenticate after upgrade.
