Multi-target net9/net10, serialization fixes, and unit tests (#18)

* Add net9/net10 targets, fix serialization bugs, and add unit tests

- Multi-target library: netstandard2.0/2.1 + net9.0 + net10.0
- Upgrade demo and new xUnit project to net10.0; CI uses .NET 10
- Preserve token order on write; default Save to UTF-8 without BOM
- Fix GetTokensFromPath NRE, Remove index handling, parser errors

* Expand unit tests with common nginx.conf directives

Add coverage for SSL, proxy, upstream, map, gzip, limit_req,
fastcgi, rewrite/try_files, types, and deeper test.conf assertions.

* Fix #15: ignore semicolons inside quoted nginx values

ParseLine now scans with quote awareness so ; # { inside
single/double quotes do not terminate statements. Adds
regression tests for add_header and related cases.
