courtmanr@gmail.com 60721cbc22 Add mutex protection for config watcher reloads (re #748)
Introduced sync.RWMutex to protect concurrent access to configuration
fields (AuthUser, AuthPass, APITokens) that are modified by the
ConfigWatcher at runtime.

- Added global config.Mu RWMutex in internal/config/config.go
- Protected config updates in ConfigWatcher.reloadConfig() and reloadAPITokens()
- Protected config reads in CheckAuth and all API token handlers
- Protected Router.SetConfig() during full config reloads

This prevents race conditions when .env file changes trigger config
reloads while authentication handlers are reading the same fields.

Internal API Package

This directory contains the API server implementation for Pulse.

Important Note About frontend-modern/

The frontend-modern/ subdirectory that appears here is:

  • AUTO-GENERATED during builds
  • NOT the source code - just a build artifact
  • IN .gitignore - never committed
  • REQUIRED BY GO - The embed directive needs it here

Frontend Development Location

👉 Edit frontend files at: /opt/pulse/frontend-modern/src/

Why This Structure?

Go's //go:embed directive has limitations:

  1. Cannot use ../ paths to access parent directories
  2. Cannot follow symbolic links
  3. Must embed files within the Go module

This is a known Go limitation and our structure works around it.
