chore: remove accidentally committed .paper-nms/ directory and add to .gitignore

[Copilot]

.paper-nms/ is a local build artifact generated by the paper-nms-maven-plugin that was accidentally committed (mappings_1.21.11.tiny.missing). It should never be tracked.

Changes

• .gitignore — adds .paper-nms/ under a new # Paper NMS section
• .paper-nms/1.21.11/mappings_1.21.11.tiny.missing — removed from git tracking (git rm --cached); local file preserved

Original prompt

Problem

The .paper-nms/ directory has been accidentally committed to the repository. Specifically, .paper-nms/1.21.11/mappings_1.21.11.tiny.missing (an empty marker file) is tracked by git. This directory is generated by the paper-nms-maven-plugin and is a local build artifact — it should never be committed.

The root cause is that .paper-nms/ is not listed in the .gitignore.

Required Changes

1. Add .paper-nms/ to .gitignore — add it under an appropriate section (e.g., Maven or a new "Paper NMS" section).
2. Remove the committed .paper-nms/ directory from git tracking — delete the files from the repository so they are no longer tracked. The files to remove are:
   • .paper-nms/1.21.11/mappings_1.21.11.tiny.missing

The local files do not need to be deleted from disk (i.e., this is effectively a git rm --cached operation), but since this is a file-based PR, simply removing the file from the repository tree is sufficient.

The following is the prior conversation context from the user's chat exploration (may be truncated):

User: This @BentoBoxWorld/BentoBox/files/.paper-nms/1.21.11 should not be in the repo afaik

Assistant: You're right — this file should not be committed to the repo. Here's what's going on:

What it is

The folder .paper-nms/1.21.11/ contains a single file:

• mappings_1.21.11.tiny.missing (empty, 0 bytes)

This is a cache/marker file generated by the paper-nms-maven-plugin, which is used to remap Minecraft NMS classes for Paper plugins. These are local build artifacts and should not be committed.

The problem

.paper-nms/ is not listed in the .gitignore, which is why it got accidentally committed.

Fix

Two things need to happen:

1. Add .paper-nms/ to .gitignore
2. Remove the committed file from the repo's history (or at minimum, untrack it)

Would you like me to open a PR that:

• Adds .paper-nms/ to .gitignore
• Removes the committed .paper-nms/ directory from tracking (via git rm --cached)?

User: yes

Assistant: We're waiting for your response to the tool call dialog to continue creating the PR.
