[TURBO] Suspend inactive background processes

[HuckleR2003]

Milestone: v1.7.5
Research: CCleaner , GeForce Experience, Advanced System Care, Performance Optimizer suspends processes, claims.
Goal: Freeze (not kill) inactive apps to free CPU/RAM.

How it works:

• Detect processes idle >5 minutes (zero CPU, no window focus)
• Suspend via NtSuspendProcess (Windows API)
• Resume when needed (user clicks, or TURBO off)

Candidates for sleep:

• Browser tabs (Chrome/Edge helper processes)
• Communication apps when minimized (Discord, Slack, Teams)
• Cloud sync (Dropbox, OneDrive when not syncing)
• Music players when paused

Blacklist (never suspend):

• System processes
• Antivirus
• Active games
• Current foreground app

Tech:

• psutil.Process.suspend() / resume()
• Track idle time via CPU samples
• State persistence (remember what we suspended)

Safety:

• Resume all on TURBO disable
• Resume on process window focus
• Timeout: auto-resume after 30min (prevent permanent freeze)

UI:

• List of suspended processes
• Manual resume button per process
• Setting: idle threshold (default 5min)

Success:

• Measurable CPU reduction (10-20% on typical system)
• No crashes from suspended processes
• User can override per-process
