fix(command-development): inconsistent backtick escaping in plugin-features-reference.md

[sjnims]

Summary

In plugins/plugin-dev/skills/command-development/references/plugin-features-reference.md, lines 396-398 use escaped backticks (!\``) while the rest of the file uses unescaped backticks (!``). This creates visual inconsistency in the examples.

Location

plugins/plugin-dev/skills/command-development/references/plugin-features-reference.md:396-398

Current (Inconsistent)

Stage changes: !\`git add $1\`

Commit changes: !\`git commit -m "$2"\`

Expected (Consistent with rest of file)

Stage changes: !`git add $1`

Commit changes: !`git commit -m "$2"`

Context

Throughout the skill documentation, the bash pre-execution syntax !command`` is shown without escaping the backticks. This section is the only place where backslash escaping is used, creating inconsistency.

Acceptance Criteria

• Remove backslash escaping from lines 396-398
• Verify consistency with other bash execution examples in the file
