docs(registries): add gsd-reasonix EoS entry (#3403)

Adds one `type: "eos"` entry for a Reasonix host integration and regenerates
docs/registries/eos-registry.md.

Reasonix is a Go, single-static-binary, DeepSeek-native terminal coding agent.
The integration renders the GSD workflow set as native Reasonix slash-command
launchers; GSD workflows are not reimplemented.

Every axis is sourced from Reasonix's own docs per the never-infer rule.
`effortSurface` is omitted: Reasonix resolves effort from config and the
/effort command with no argv route, so neither allowed value fits and the
field is optional.

Supersedes #3346, which proposed an in-tree capabilities/reasonix entry and
was closed as filed against the wrong surface.
