What problem(s) was I solving?

Fixes incorrect log file path display in Settings for CodeLayer PRO and other build variants. Previously hardcoded to "codelayer.log", now dynamically uses the product name (e.g., "CodeLayer-Pro.log", "CodeLayer-Nightly.log").

Fixes #884

What user-facing changes did I ship?

No new user-facing changes.

How I implemented it

Changes Made

1. Added new Rust command (humanlayer-wui/src-tauri/src/lib.rs:315-328):

   • Created get_log_file_name() command that dynamically returns the correct log file name based on the Tauri product name
   • In development mode: always returns codelayer.log
   • In production mode: returns {ProductName}.log (e.g., CodeLayer-Pro.log, CodeLayer-Nightly.log, or CodeLayer.log)

2. Updated TypeScript code (humanlayer-wui/src/components/SettingsDialog.tsx:69-85):

   • Modified loadLogPath() function to call the new get_log_file_name command
   • Now dynamically constructs the full log path using the correct filename for each build variant

3. Updated documentation (humanlayer-wui/CLAUDE.md:5-14):

   • Documented the correct log paths for all build variants (Standard, Nightly, and PRO)

How It Works

The fix leverages the fact that Tauri automatically uses the productName from the config as the log file name when file_name: None is set in the log plugin configuration. The new code:

• Reads the product name from Tauri's config at runtime
• Formats it as {ProductName}.log
• Returns the correct filename for each build variant:
  • Standard: CodeLayer.log
  • Nightly: CodeLayer-Nightly.log
  • PRO: CodeLayer-Pro.log

How to verify it

Testing

1. Built the dev version of CodeLayer
2. Went to Settings
3. Verified the log path shows: ~/Library/Logs/dev.humanlayer.wui.pro/codelayer.log
4. Tested the "Copy last N lines" button to ensure it correctly reads from the log file

• I have ensured make check test passes

I did get a failure on the daemon lint checks, but assume this was already present?
