feat(charts): Add V1 conversation API settings to openhands chart

[jpshackelford]

Summary

This PR adds configurable settings for V1 conversation API feature flags to the OpenHands Helm chart. These settings prepare the charts for upcoming OpenHands releases (1.0.0+) that include V1 conversation support.

Changes

New Configuration Options (values.yaml)

Added a new v1Conversations section with the following settings:

Setting	Environment Variable	Default	Description
enableV1Routes	ENABLE_V1	"true"	Server-level switch that controls whether V1 API routes (/api/v1/*) are mounted
defaultV1Enabled	V1_ENABLED	"0"	Default setting for new users - determines if their conversations use V1 API
enableV1GithubResolver	ENABLE_V1_GITHUB_RESOLVER	"false"	Controls whether GitHub integration uses V1 conversations
enableV1SlackResolver	ENABLE_V1_SLACK_RESOLVER	"false"	Controls whether Slack integration uses V1 conversations

Default Behavior

With these defaults:

• V1 API routes are available (ENABLE_V1=1) - clients can use V1 endpoints if they choose
• All conversations start as V0 (V1_ENABLED=0) - new users default to legacy V0 conversations
• Integrations use V0 - GitHub and Slack resolvers use V0 conversation API

This provides a safe upgrade path where V1 is available but not enabled by default.

Code References (from OpenHands repo)

These settings map to the following code in OpenHands:

1. ENABLE_V1 - openhands/server/config/server_config.py:41

   enable_v1: bool = os.getenv('ENABLE_V1') != '0'

2. V1_ENABLED - openhands/storage/data_models/settings.py:54

   v1_enabled: bool | None = Field(default=bool(os.getenv('V1_ENABLED') == '1'))

3. ENABLE_V1_GITHUB_RESOLVER / ENABLE_V1_SLACK_RESOLVER - enterprise/integrations/utils.py:80-85

   ENABLE_V1_GITHUB_RESOLVER = os.getenv('ENABLE_V1_GITHUB_RESOLVER', 'false').lower() == 'true'
   ENABLE_V1_SLACK_RESOLVER = os.getenv('ENABLE_V1_SLACK_RESOLVER', 'false').lower() == 'true'

Chart Version

Bumps chart version from 0.1.35 to 0.1.36.

Testing

To enable V1 conversations for all new users, override in your values:

v1Conversations:
  defaultV1Enabled: "1"

To enable V1 for GitHub resolver:

v1Conversations:
  enableV1GithubResolver: "true"
