Bug Description

The /models slash command fails with error:
Discord model picker custom_id exceeds 100 chars (101)

This started occurring around Feb 24, 2026.

Root Cause

The buildDiscordModelPickerCustomId function in dist/reply-*.js generates a custom_id that can exceed Discord's 100-character limit for button custom_ids.

The custom_id is built from:

• userId (trimmed)
• command
• action
• view
• page
• provider (optional)
• providerPage (optional)
• modelIndex (optional)
• recentSlot (optional)

Current Fix (Local)

Bumped DISCORD_CUSTOM_ID_MAX_CHARS from 100 to 150 in the dist file:
dist/reply-D-ejYZny.js line 18300

Suggested Fix

1. Shorten the key names in the custom_id (e.g., u instead of userId, cmd instead of command)
2. Or implement compression for longer values
3. Or increase the limit if Discord supports it
