Add getting started, SSH guide, and PLR Z-offset fix

[jakenbake350]

Summary

• Adds content/getting-started/README.md — basic intro page for new Q2/Q2C owners
• Adds content/ssh-guide/README.md — how to connect via SSH on Windows/macOS/Linux, covering built-in terminal plus Bitvise, PuTTY, and MobaXterm
• Adds content/plr-z-offset/README.md — documents the PLR resume bug where plr.sh overwrites the Z offset set by set_zoffset, with root cause explanation and a one-line fix

Test plan

• Verify markdown renders correctly on GitHub
• Confirm file paths follow content/<topic>/README.md convention
• PLR fix tested on Q2 with custom z_offset in saved_variables.cfg

Can we not infest the wiki with LLM slop please?

The SSH and getting-started guides exist to link new users to in Discord instead of walking every single person through the same basic setup steps. That's the whole point — save time, not spend more of it. They're meant to be short and to the point, not comprehensive.

I don't know GitHub markdown. I tried formatting it myself first, took an hour or two, looked horrible. So I had AI clean up the formatting. It reminded me of writing in LaTeX which I used for 7 years and can't even remember these days. The content is mine. If you wanted to see slop my original drafts were unreadable.

The PLR Z-offset fix isn't AI-written info — I hit that bug, root-caused it, and verified the fix independently on both my Q2 and Q2C (firmware 1.1.0 and 1.1.1). AI wrote up the page, but the fix and testing are mine.

If this wiki doesn't want AI-assisted formatting regardless of the content being accurate and tested, that's a fair call to make — just tell me and I'll know not to bother next time. I wouldn't go through the trouble of writing all this up if it wasn't accurate and useful.

Unreadable Markdown is not slop, it's just unreadable Markdown.

I promise you, people who care about quality much rather have you submit unreadable Markdown and help you fix that up, instead of having some LLM slopify it.
