Fix SSH console line endings on Unix

[ST3FAN-dev]

Fixes #301

What changed

Normalize bare LF (\n) line endings to CRLF (\r\n) before writing console output to the built-in SSH terminal.

Existing CRLF sequences are preserved.

Why

On Unix/Linux hosts, forwarded Minecraft/Paper console output uses LF-only line endings. The SSH terminal receives those bare LF characters unchanged, which causes the cursor to move down without returning to column 0 ("stair-step" output).

On Windows, the issue was not visible because the forwarded output already used CRLF.

Tested

• Debian Trixie host + original build: issue reproduced
• Debian Trixie host + patched build: output is correct
• Windows host + original build: output is correct
• Windows host + patched build: output remains correct

Also tested through the built-in AutoPlug SSH console.

Hi @Osiris-Team,

I prepared 12 JUnit 5 regression tests for #302, preserving ST3FAN-dev's fix and credit. In an isolated harness, the actual production class fails 10 cases before the fix and passes all 12 afterward. This used dependency/test-runner stubs; full project CI and live SSH checks remain pending.

Would you fund this separate test-only contribution for EUR 5 gross via PayPal, payable on acceptance and merge? #301 has no bounty assigned, so I am checking before submitting a claim.

The work is Codex-assisted; I would complete project checks and account-owner review before a PR. Can payout details be shared privately?
