[autofix] instagram/explore: empty result (explore_grid response shape drift)

[Ro-28]

Summary

OpenCLI autofix repaired this adapter locally, and the retry passed.

Adapter

• Site: instagram
• Command: explore
• OpenCLI version: 1.8.6

Original failure

• Error code: (no error thrown — returned empty [])

instagram explore returned [] despite HTTP 200 from
/api/v1/discover/web/explore_grid/ — the adapter only read
sectional_items[].layout_content.medias[], which IG no longer populates.

Local fix summary

IG changed the explore_grid response: media are no longer under the flat
layout_content.medias[] path — they are nested across mixed layout shapes
(one_by_two_item.clips.items[].media, fill_items[], etc). Fix: recursively walk
sectional_items collecting every distinct node.media (dedupe by pk/id/code),
then map to rank/user/caption/likes/comments/type. Also fall back to play_count
for likes on clips/reels. Verified: returns 20 posts.
