Add !uptime prefix command to display bot runtime

[TrivCodez]

Description

Create a prefix command !uptime that shows how long the bot has been running since its last restart.

Task

• Create prefixcommands/uptime.py
• Track bot start time using time.time() or datetime
• Calculate elapsed time (days, hours, minutes, seconds)
• Format output as: Uptime: X days, Y hours, Z minutes
• Follow existing pattern from prefixcommands/ping.py

Why this is good for beginners

• Teaches time calculation and formatting
• Introduces global state management
• Simple math operations
• Builds on existing command patterns
• Immediate visual feedback

Example output

Bot Uptime: 2 days, 14 hours, 35 minutes

Files to modify

• Create: prefixcommands/uptime.py
• Modify: bot.py (add start_time variable and extension)

Acceptance Criteria

• Command responds to !uptime
• Shows accurate elapsed time
• Works in both guilds and DMs
• Format is human-readable
• Code follows existing style with type hints
• Bot start time persists across commands
• Tested by running bot for several minutes
