fix(twitter): preserve text when posting images

[hanzili]

Summary

• upload images before inserting tweet text so X's composer re-render cannot erase Draft.js content
• use the current /compose/post route and explicit composer/file input readiness checks
• insert text with native browser input when available, fall back to DOM events, and verify text before clicking Post
• wait for submission completion instead of reporting success immediately after click
• add adapter regression coverage for image posting order, upload timeout, fallback text insertion, and validation paths

Test Plan

• npx vitest run --project adapter clis/twitter/post.test.js clis/twitter/reply.test.js
• npm run build
• git diff --check

Background

While using opencli twitter post "text" --images image.jpg, the command could report success while the resulting tweet was missing text/media. X's composer can reset the Draft.js editor while media is attaching, so the command now attaches media first and verifies the final composer state before posting.

Live-tested the patched local build against X with an actual image upload.

Result verified on the profile:

• text preserved
• media attached
• URL: https://x.com/hanzi_li/status/2048095554240913879

The live test exposed one extra edge case: X can publish successfully while stale composer/media nodes remain visible long enough for the CLI's submission-complete heuristic to time out. I updated the PR to:

• prefer the Page nativeType CDP insertion helper before the older bridge insert-text path
• treat X's success toast as completion even when stale composer nodes remain
• add regression coverage for both cases

Updated local verification:

• npm run build
• npx vitest run --project adapter clis/twitter/post.test.js clis/twitter/reply.test.js → 20/20 passing
• git diff --check
