Update language server plugin to exclude base file diagnostics for file hooks

[lL1l1]

Description of the proposed changes

Disable diagnostics for the base file that is being hooked so that errors in that file don't show up when editing your hook.

Testing done on the proposed changes

I've used this plugin when developing mods.

You can also view what the plugin's text replacement is creating by going to LOGPATH/diffed.lua (https://luals.github.io/wiki/plugins/) when develop=true in the misc parameters (as in the debug setup commit). The normal log file is linked in the vscode's output panel (ctrl+shift+u) in the lua category when the language server starts, which leads to the LOGPATH folder.

The FA Lua plugin now logs startup progress and wraps repository hook content with diagnostic directives before passing it to the language server. Changelog snippets document the plugin update and remove placeholder text.

The reason I replace with text:sub(1,1) is that I can't make start and finish equal 0. You have to replace some byte, you can't just add in content.

In @.vscode/fa-plugin.lua:
- Around line 77-85: The diagnostic-enable directive assembled in the diff
insertion must always begin on its own line. Normalize repoContent after reading
it in the surrounding hook logic, ensuring a trailing newline is present before
concatenating diagnosticEnable, and add a regression case covering repository
files without a final newline.
- Around line 75-77: Close the file handle in the repoFile flow after
repoFile:read("*a") completes. Add repoFile:close() immediately after reading,
while preserving the existing content-processing behavior.
