chore: release CLI 0.1.5

[Fermionic-Lyu]

Version bump for the 0.1.5 release: insta feedback proves who is sending on InstaCloud production, so the report opens a support ticket (#288). The platform (instacloud-platform#534) and the feedback service (instacloud-feedback#29) are both live, and an end-to-end report from main opened its ticket.

After merge: push tag v0.1.5 on the merge commit. The release workflow publishes npm and the GitHub binaries.

Unblocks instacloud-skills#125 (agent docs, held for this release).
