[Bug]: Chat input: spellcheck and macOS text replacements no longer work after update

Before submitting

• I searched existing issues and did not find the same problem.
• I have read the relevant documentation (e.g., the README) but could not resolve this issue.

Problem

Environment

• Claudian: v2.3.0 (installed via BRAT v2.2.0)
• Claude Code: v2.1.153
• Obsidian: 1.13.7
• macOS: Tahoe 26.5.2 (MacBook Air M2, 2022)

Problem
Since the latest update, macOS text replacements (System Settings → Keyboard → Text Replacements)
no longer work in the Claudian chat input field. Spellcheck is also inactive there
(misspelled words are not underlined).

In the regular Obsidian editor, both spellcheck and text replacements work fine
(Obsidian spellcheck enabled, macOS spelling set to "Automatic by language"),
so the issue is specific to the Claudian input field.

It worked before the update.

Steps to reproduce

Steps to reproduce

1. Define a macOS text replacement, e.g. ";;fr" → "ja, freigabe für deine empfehlung"
2. Type ";;fr" + space in an Obsidian note → replacement works
3. Type ";;fr" + space in the Claudian chat input → nothing happens
4. Type a misspelled word in the Claudian chat input → no red underline

Expected behavior

Expected
The chat input should keep spellcheck enabled (e.g. spellcheck="true" on the textarea),
or offer a setting to enable it, so native macOS text replacements work.

Environment

• Obsidian version:
