fix: free-form questions render a visible text input (#349)

[jeonghun-jj-lee]

Problem

When the agent asks a free-form question (kind: "text"), no textarea appears for the user to type their answer. The question text and footer buttons render, but the input area is invisible.

Root cause

The opencode commit c1e4862d (PR #143, file-reference resolution) accidentally deleted the [data-slot="question-text-form"] CSS rules that had been added by PR #124 (fix opencode#121). These rules gave the text-card textarea its:

• border (1px solid)
• background (layer-02 surface)
• border-radius (radius-md)
• min-height (36px)
• padding (8px 12px)

Without them, the textarea inherits the choice-card's transparent/borderless custom-input style — invisible.

Fix

Restores the deleted CSS in the opencode engine (harmoniqs/opencode#191) and bumps the vendored binary pin to include it. A regression test in the opencode repo asserts the selectors remain present.

Dependencies

• fix(session-ui): restore text-card question CSS (amicode#349) opencode#191 (the CSS fix + regression test)

Once that PR merges and a release is cut, this lock should be bumped from source:"local" to source:"release" with the new tag.

Testing

• opencode: bun test packages/session-ui/src/components/message-part-css.test.ts — 4/4 pass
• opencode: bun test packages/app/src/pages/session/composer/session-question-dock.helpers.test.ts — 6/6 pass
• opencode: typecheck clean (turbo)
• amicode: vitest run test/opencode_config.test.ts — 24/24 pass
• amicode: local binary smoke-tested (--version → 1.18.10)

Closes #349
