Fix statusline to show actual current model instead of hardcoded Opus 4.5

[thewoolleyman]

Problem

The claude-flow hooks statusline command was showing a hardcoded "Opus 4.5" model name regardless of which model the user was actually using in Claude Code. This caused confusion when users switched models (e.g., to Sonnet or Haiku) but the statusline continued to display "Opus 4.5".

Root Cause

In v3/@claude-flow/cli/src/commands/hooks.ts, the getUserInfo() function had:

const modelName = 'Opus 4.5';

There was no detection of the actual model from Claude Code's session state.

Solution

Updated the getUserInfo() function to:

1. Read ~/.claude.json to find the current project's lastModelUsage
2. Prefer the most specific path: When multiple project paths match, choose the longest (most specific) one
3. Calculate total token usage: Include cache tokens (cacheReadInputTokens + cacheCreationInputTokens) to accurately determine the most-used model
4. Parse model ID: Convert model IDs like claude-sonnet-4-5-20250929 to human-readable names like "Sonnet 4.5"
5. Fallback gracefully: Show "Unknown" if detection fails

Changes

• Added os import for accessing home directory
• Replaced hardcoded const modelName = 'Opus 4.5' with let modelName = 'Unknown'
• Added model detection logic that:
  • Finds the most specific matching project path
  • Calculates total token usage including cache tokens
  • Maps model IDs to display names (Opus 4.5, Sonnet 4.5, Sonnet 4, Haiku 4.5)

Testing

Tested with:

• User switching from Opus to Sonnet → statusline correctly shows "Sonnet 4.5"
• Nested project directories → correctly prefers specific project path over parent
• Multiple models used in session → shows the most-used model by token count

Impact

• Users will now see their actual current model in the statusline
• Works correctly across all Claude models (Opus, Sonnet, Haiku)
• Handles edge cases like nested project directories

Screenshot

Before:

▊ Claude Flow V3 ● user  │  ⎇ main  │  Opus 4.5

After (when using Sonnet):

▊ Claude Flow V3 ● user  │  ⎇ main  │  Sonnet 4.5
