fix(cli): treat existing channel as success on channel add - #3195
Conversation
When createChannel fails with unique_name_app_id, verify the channel is readable with the same API key and return success instead of throwing. RBAC, 5xx, and network errors remain real failures for PostHog tracking. Analogous to app add idempotency (#3186); not the CliUserError silencing approach from #3179.

📝 WalkthroughWalkthroughThe CLI now classifies duplicate channel creation errors by channel readability. Readable duplicates recover successfully, inaccessible duplicates return a specific error, and unverifiable access returns a permission error. Tests cover these outcomes. ChangesChannel duplicate recovery
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to When an existing channel is recovered successfully, the command may return a different success response shape than a newly created channel, which could affect callers that rely on additional response fields. The PR is mergeable with explicit owner awareness and a follow-up to preserve the normal response shape. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

addChannelInternalnormally returns response data plusnameat Lines 179-180, but this branch returns onlyname. Callers that readstatusor another response field will receive a different result when recovery succeeds.Return the same success shape for both paths.
Proposed fix
- return { name: channelId } + return { status: 'ok', name: channelId }As per coding guidelines, public API and plugin changes must remain backward compatible: do not remove or change existing fields, meanings, formats, or status codes.

PostHog Capgo project 22029 shows recurring CLI exceptions for duplicate channel creation:

Contrast with #3179: that PR only reclassifies 4xx errors as
