[FEATURE] Option to disable auto-newline after slash command/skill input

• [x] This is a single feature request (not multiple features)

Problem Statement

When typing a skill name (e.g. /evaluate, /sweep) in the input field, a newline is automatically inserted after the skill is recognized. This forces the skill invocation and any following text onto separate lines.

Since skills are already visually distinct (blue font + / prefix), the auto-newline adds no clarity — it just adds friction when composing prompts that combine a skill with inline context, e.g.:

/evaluate claude-code-dashboard

Proposed Solution

Request: Make the auto-newline behavior configurable, either via a setting in settings.json or by removing it entirely. The visual styling is sufficient to distinguish skill names from regular text.
