Subject: [PATCH] Fix: Add missing --index option to argument parser (#84)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Fix: Add missing --index option to argument parser

The --index flag was documented and used in code but not defined
in parseArgs options, causing it to be ignored. Now properly handles
custom index names like: qmd --index test status

* Feature: Use index name for config files too

Now --index <name> loads ~/.config/qmd/<name>.yml instead of index.yml.
This allows completely separate indexes with their own collections.

Example:
  qmd --index hackage status
  → Uses ~/.config/qmd/hackage.yml + ~/.cache/qmd/hackage.sqlite

Moved hackage collection to hackage.yml for separation.
