Consider renaming package to opencode-workspaces

[athal7]

Context

The plugin now supports both devcontainers and git worktrees for branch isolation. The name opencode-devcontainers no longer accurately reflects the full scope of functionality.

Proposal

Rename the npm package from opencode-devcontainers to opencode-workspaces.

Implementation Considerations

1. npm rename process:

   • Publish new package opencode-workspaces
   • Deprecate old package opencode-devcontainers with message pointing to new name
   • Update README with migration instructions

2. Environment variables:

   • Add new OCW_* prefix support
   • Keep backward compatibility for OCDC_* prefix
   • Auto-migrate config/cache paths from old locations

3. Config paths:

   • New: ~/.config/opencode/workspaces/config.json
   • Old: ~/.config/opencode/devcontainers/config.json
   • Auto-migrate on first run

4. Breaking change:

   • Users must update their opencode.json to use the new package name
   • This warrants a minor version bump in 0.x (0.3.0)

Questions

• Is the rename worth the disruption for existing users?
• Should we wait until more features justify the rename?
• Alternative names considered: opencode-branches, opencode-isolation

Decision

Leave this issue open for discussion. Close with either:

• Implementation PR if we proceed
• "wontfix" if we decide the current name is fine
