Problem: static_enums was a manually maintained table of ~40 keywords
that could go stale when OpenSSH adds or changes config options.
Solution: parse enum values directly from the ssh_config man page using
two strategies: definitive list sentences ("The argument must be X, Y,
or Z") and fallback extraction from "set to X" patterns. Also fixes
keyword detection to handle digits (ForwardX11) and inline definitions
(Tunnel, SetEnv). Covers 36/41 old keywords plus discovers 4 new ones
(IPQoS, SyslogFacility, ObscureKeystrokeTiming, ControlPersist).
Problem: keywords with description text on the same line (e.g.
"Host Restricts the following...") had their first line of
documentation silently dropped because the parser started collecting
at the line after the keyword.
Solution: extract trailing text from the keyword line and prepend it
to the description block.
Problem: the existing blink-cmp-sshconfig plugin uses a synchronous,
build-time Python scraping approach that requires uv and make to
generate a static Lua file.
Solution: implement a runtime, async blink.cmp source that parses
ssh_config keywords from man ssh_config and enum values from ssh -Q
queries, matching the architecture of blink-cmp-tmux and
blink-cmp-ghostty.
