Ensure .dappnode_profile is sourced in all shell environments

[Copilot]

DAppNode commands were not available in some installations because the .dappnode_profile file was only being added to .profile, but many interactive shell sessions use .bashrc instead.

Problem

The installation script only added profile sourcing to the .profile file:

echo -e "source ${DAPPNODE_PROFILE}\n" >>$PROFILE

This caused issues because:

• Interactive bash sessions (SSH, terminal apps) typically source .bashrc
• Login shells source .profile
• Different shell configurations have varying sourcing behaviors

As a result, users would find that DAppNode commands like dappnode_help, dappnode_status, etc. were not available in their shell sessions.

Solution

Enhanced both installation and uninstallation scripts to handle both .profile and .bashrc files:

Installation (scripts/dappnode_install.sh):

# Add profile sourcing to both .profile and .bashrc for maximum compatibility
for config_file in .profile .bashrc; do
    CONFIG_PATH="$USER_HOME/$config_file"
    
    # Create config file if it doesn't exist
    [ ! -f "$CONFIG_PATH" ] && touch "$CONFIG_PATH"
    
    # Add profile sourcing if not already present
    if ! grep -q "${DAPPNODE_PROFILE}" "$CONFIG_PATH"; then
        echo "########          DAPPNODE PROFILE          ########" >>"$CONFIG_PATH"
        echo -e "source ${DAPPNODE_PROFILE}\n" >>"$CONFIG_PATH"
    fi
done

Uninstallation (scripts/dappnode_uninstall.sh):

# Remove profile file references from shell config files
for config_file in .profile .bashrc; do
    CONFIG_PATH="$USER_HOME/$config_file"
    if [ -f "$CONFIG_PATH" ]; then
        sed -i '/########          DAPPNODE PROFILE          ########/d' "$CONFIG_PATH"
        sed -i '/.*dappnode_profile/d' "$CONFIG_PATH"
    fi
done

Benefits

• Universal Compatibility: Works with both login shells (.profile) and interactive shells (.bashrc)
• Idempotent: Running installation multiple times doesn't create duplicate entries
• Clean Removal: Uninstallation removes all references from both files
• Shell Agnostic: Works regardless of default shell (bash, zsh, etc.)
• Backwards Compatible: Enhances existing behavior without breaking current functionality

Users will now have access to all DAppNode commands in any shell environment without requiring manual configuration.

Fixes #664.
