fix(claude): support Claude Desktop transcript format

[WenhuaXia]

Summary

• Claude Code Desktop writes JSONL entries with a top-level type: 'assistant' field instead of message.role: 'assistant'
• The session parser only checked message.role, causing all assistant messages to be silently skipped
• Users see no replies in the chat UI when using sessions from Claude Code Desktop

Fix

Check both raw.message?.role === 'assistant' and raw.type === 'assistant' to support both CLI and Desktop transcript formats.

Test plan

• Install ClaudeCodeUI with Claude Code Desktop sessions and verify assistant messages are displayed
• Verify CLI sessions (with message.role) still work correctly

📝 Walkthrough

Walkthrough

The PR extends transcript format detection in the Claude sessions provider to support both CLI-style (message.role) and Desktop-style (type) assistant markers. Two functions that identify and normalize assistant entries now check both condition patterns to handle both transcript shapes.

Changes

Transcript Format Support Expansion

Layer / File(s)	Summary
Assistant Entry Detection server/modules/providers/list/claude/claude-sessions.provider.ts (lines 53-60)	parseAgentTools now identifies assistant entries when either entry.message.role === 'assistant' or entry.type === 'assistant', broadening which entries are scanned for tool_use parts.
Assistant Message Normalization server/modules/providers/list/claude/claude-sessions.provider.ts (lines 352-358)	normalizeMessage applies the same dual-condition check (`raw.message?.role === 'assistant'

Poem

🐰 A rabbit's ode to flexibility:

Two formats, one provider—what joy!
Both CLI and Desktop now play,
Assistant entries dance either way,
With role or type deployed,
No transcript left behind today! 🎉
