Problem: LuaLS struggles with the generics used in Nvim's runtime,
requiring broad diagnostic suppressions. Indexing is also slow.
Solution: Use EmmyLua for type checks in the build and CI. It offers
more sophisticated type checking, substantially better support for
generics, and much better flow analysis.
Correct the affected annotations. Use `@internal`, supported directly by
EmmyLua, instead of `@nodoc` for shared internal declarations, and
support it in the help parser.

Problem:
`parse_ssh_config()` compares tables against a freshly allocated empty
table.
- In `parse_multiple_values()`, the guard which avoids flushing an empty
accumulator never applies. Runs of separators and trailing whitespace
push empty strings into the results, and `is_valid()` does not filter
them. `Host alpha beta ` parses as `{ 'alpha', '', 'beta' }`.
- In `parse_value()`, the condition reduces to `chr == '"' and quoted`.
`quoted` starts false and only that branch sets it, so it can never
become true: quotes are never recognised and are inserted literally,
and the unterminated-quote check is unreachable.
Solution:
Compare `#val` instead. Add a test for repeated and trailing separators.
