feat: Data & Storage section in General Settings (#378)

[jeonghun-jj-lee]

Summary

Adds a Data & Storage section in the General tab of the settings dialog with two path fields:

• Session database — override path for the opencode session database (OPENCODE_DB)
• Configuration directory — override path for the opencode config directory (OPENCODE_CONFIG_DIR)

Both fields show resolved XDG defaults as placeholder text, validate on blur (absolute paths required, parent dir must exist for DB, directory must exist for config dir), and trigger a server restart on valid change. Overrides persist across sessions.

Changes

New files

• data-storage-controller.ts — controller: queries defaults on mount, dispatches updates on blur, listens for status replies
• data-storage.tsx — UI component: section header + 2 TextInputV2 path fields with inline error display

Modified files

• general.tsx — renders DataStorageSection between Display and Advanced sections
• context/settings.tsx — adds storage.{databasePath, configDir} to Settings interface + defaults + getters/setters
• i18n/en.ts — adds i18n keys for section title, field titles, descriptions, and error messages

Warning

Review limit reached

@jeonghun-jj-lee, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 5 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
