fix(mobile): show full markdown read bodies

[iscekic]

User: Tapping a markdown read row now opens the details sheet with the full available markdown immediately. The removed “Tap to read the full file” prompt and nested reader are gone.

Product manager: Markdown read output now uses one direct sheet interaction, while image zoom and other tool output behavior remain unchanged.

Maintainer: The mobile read resolver now returns a full fence-balanced MarkdownBody. ReadMarkdownBody renders it with the existing selectable chat markdown component, and the obsolete modal and inline-cap fields were removed.

Human steps: No step is needed before or after merge.

Visual Changes: N/A

E2E: bot-e2e — scenario 1 gates direct full markdown rendering; scenario 2 checks the unchanged inline image path and can report a fixture block reason.

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Executive Summary

Reviewed the mobile read-tool markdown refactor (resolver rename/simplification, new ReadMarkdownBody sheet component, removal of the modal viewer and inline cap, and updated tests) with high confidence: no stale references to removed symbols, no orphaned exports, edge cases (empty file, error state, image reads, fence balancing) preserved and covered by tests, the detail sheet scrolls so full markdown is reachable, and no memory-leak vectors were introduced (new component is stateless; the deleted preview's modal state is gone).
