fix: Fish completion script corrupted by INFO log message

[jhult]

Bug

Fish completion script has an INFO log message at the start of the file, which breaks the shell script syntax:

INFO Loading configuration from file: .licenserc.yaml
# fish completion for license-eye...

This causes fish to error: 'end' outside of a block when sourcing the completion file. Example:

❯ license-eye header /opt/homebrew/share/fish/vendor_completions.d/license-eye.fish (line 39): 'end' outside of a block
    end
    ^~^
from sourcing file /opt/homebrew/share/fish/vendor_completions.d/license-eye.fish
source: Error while reading file ['/opt/homebrew/share/fish/vendor_completions.d/license-eye.fish'](url)

Root Cause

The PersistentPreRunE hook in commands/root.go loads the config file, which logs an INFO message before the completion script is generated. When running license-eye completion fish, the config loading happens before outputting the completion script.

The issue manifests in two ways:

1. When generating the completion file directly
2. During actual completion when cobra internally calls __complete command

Fix

Skip config loading in PersistentPreRunE for both:

• The completion parent command
• The __complete command used internally by cobra
