Add support for .yamltectureignore to --mergeConfig

[Copilot]

The --mergeConfig command merges all YAML files in a folder, but there was no way to exclude specific files. This adds .yamltectureignore support using gitignore syntax.

Changes

• internal/configuration/load.go: LoadFolder now checks for .yamltectureignore in the target folder and skips matching files
• Dependency: Added github.com/sabhiram/go-gitignore for pattern matching
• Documentation: Updated docs/COMMANDS.md with usage examples
• Tests: Added tests/ignore/ test case

Usage

Place a .yamltectureignore file in the config folder:

# Ignore specific files
example.yaml
temp-*.yaml

Then run:

yamltecture --mergeConfig -in ./configs

Files matching patterns are excluded from the merged output.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• dl.google.com
  • Triggering command: /update-job-proxy /update-job-proxy int (dns block)
  • Triggering command: /update-job-proxy /update-job-proxy DROP .9/x64/codeql/to/etc/ssl/certs/ce5e74ef.0 test -e cation_Authority.pem .9/x64/codeql/to-e test ckages/lib:/usr/git mpile .9/x64/codeql/to-fx test -e CA_v1.pem /home/REDACTED/go/-e /usr/bin/test -unreachable=fal/usr/sbin/iptables ignore support t--wait by/13b01b8f89eb8-t test (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

This section details on the original issue you should resolve

<issue_title>Add support for .yamltectureignore to --mergeConfig</issue_title>
<issue_description>By default the --mergeConfig combines all YAML files into a consolidated config file. However, it may be possible that you don't want all YAML files in that folder to be combined. That is where a .yamltectureignore file would come in useful. This file would contain a list of the files to be ignored by the command. This new file type should use the same syntax and approach of .gitignore files, just being used by the .yamltectureignore.</issue_description>
