[DOCS] Interactive mode and output styles docs still present `/output-style` as standard command after deprecation

Documentation Type

Incorrect/outdated documentation

Section/Topic

Built-in command reference and output style workflow after /output-style deprecation.

Current Documentation

The interactive command table currently states:

| /output-style [style] | Switch between output styles ... |

And Output styles currently instructs:

Run /output-style to access a menu and select your output style Run /output-style [style], such as /output-style explanatory, to directly switch to a style

What's Wrong or Missing?

Changelog v2.1.73 says /output-style is deprecated in favor of /config, and output style is fixed at session start for prompt-caching consistency.

Current docs still present /output-style as the primary/normal workflow and do not explain session-start immutability, which can cause users to expect mid-session switching that no longer applies.

Suggested Improvement

Update Interactive mode and Output styles docs to:

• Mark /output-style as deprecated (or remove from primary command table)
• Point users to /config for selecting output style
• Explicitly document that output style is fixed at session start and when the new style takes effect
• Add migration guidance for users/scripts that previously invoked /output-style

Impact

Medium - Makes feature difficult to understand
