Enhanced default behavior: Automatic GoPro SD card detection and firmware management

## Summary

Enhanced the default behavior of goprox to automatically detect and manage GoPro SD cards when run without parameters. This provides a comprehensive GoPro SD card management experience in a single command.

## Requirements

- When goprox - import and process GoPro media files

Usage: goprox [commands] [options] [advanced options] ...

Commands:
-a, --archive archive source sdcard
-i, --import import media files
-p, --process process imported files
default: process imported files since last process run
all: process all imported files
val[ymwdHMS]: process files modified within the specified time period
--clean clean up source sdcard
checks if source is a GoPro sdcard format
--firmware update sdcard to the latest GoPro official firmware version
--firmware-labs update sdcard to the latest GoPro Labs firmware version
--geonames add geonames information to imported directories to enable time processing
--mount trigger mountpoint processing
will search for GoPro media card mountpoints and kick of processing
this is also leveraged by the goprox launch agent
--setup run program setup
--test run program tests
this option is reserved for developers who clone the GitHub project

Options:
-h, --help show this help message and exit
-c, --copyright add copyright information to processed files
-l, --library specify library directory
-s, --source specify source directory for media files commonly .
-t, --timeshift adjust timestamps of imported files
-q, --quiet run program quietly
-v, --verbose run program verbosely
--config specify config file
defaults to ~/.goprox
--debug run program in debug mode
--time specify time format for output
format: specify time format for output
--version show version information and exit

Advanced Options:
--if specify conditional processing
condition: specify condition for processing
--created-on filter files by creation date
date: filter files created on the specified date
--created-after filter files by creation date
date: filter files created after the specified date
--created-before filter files by creation date
date: filter files created before the specified date
--modified-on filter files by modification date
date: filter files modified on the specified date
--modified-after filter files by modification date
date: filter files modified after the specified date
--modified-before filter files by modification date
date: filter files modified before the specified date
--repair repair imported files time information
created: repair file creation dates

For more detailed documentation type: man goprox or visit https://github.com/fxstein/GoProX is run without any parameters, it should scan all mounted volumes for GoPro SD cards
- Automatically detect firmware type (official vs Labs) based on version suffix
- Check for newer firmware versions and offer updates
- Propose volume renaming with shortened names based on camera type and serial number
- Provide comprehensive information about each detected card
- Show summary of all actions taken

## Motivation

Previously, users had to run multiple commands or use specific flags to manage GoPro SD cards. The new default behavior makes goprox more user-friendly and provides immediate value when users insert a GoPro SD card.

## Acceptance Criteria

- [x] Scan all mounted volumes for GoPro SD cards
- [x] Extract and display camera information (type, serial number, firmware version)
- [x] Detect firmware type automatically (official vs Labs based on version suffix 70-79)
- [x] Check for newer firmware in appropriate repository (official vs Labs)
- [x] Offer firmware updates with confirmation prompts
- [x] Propose volume renaming with shortened names (CAMERA_TYPE-SERIAL_LAST_4)
- [x] Suppress redundant output when volume name is already correct
- [x] Detect existing firmware update files to avoid repeated prompts
- [x] Show comprehensive summary of all actions taken
- [x] Handle both renaming and firmware updates in single session

## Technical Implementation

### Firmware Type Detection
- **Official firmware:** Ends with (e.g., H22.01.01.10.00)
- **Labs firmware:** Ends with to (e.g., H22.01.01.10.70)

### Volume Naming Convention
- Format:
- Example: (from HERO11 Black with serial ending in 8909)
- Removes "Black" from camera type names for brevity

### Smart Detection Features
- Automatically checks correct firmware repository based on current firmware type
- Downloads and caches firmware files
- Extracts update files to SD card UPDATE directory
- Creates marker files to prevent duplicate processing
- Detects existing UPDATE directories to avoid repeated prompts

## Example Output

```
Scanning for GoPro SD cards...
Found GoPro SD card: HERO11-8909
Camera type: HERO11 Black
Serial number: C3471325208909
Firmware version: H22.01.01.10.70
Firmware type: labs
Firmware update already prepared (UPDATE directory exists)

Summary: Found 1 GoPro SD card(s)
- 1 already correctly named
SD card detection finished.
```

## Reference

This feature builds upon the existing firmware management and SD card detection capabilities, integrating them into a seamless default experience.
