3 people a0825689f3 zip: Static file handler + composable Middleware (With/Chain) — additive (#6) ...

Two additive capabilities on the zip surface, neither touching the existing
Use(Handler...) c.Next model.

Static(fs.FS, ...StaticOption) — leaf file handler for a wildcard route.
Serves the "*" subpath from any fs.FS (embed.FS or os.DirFS); path.Clean +
fs.ValidPath reject traversal fail-closed (404); a missing file calls c.Next()
so a later route or SPA catch-all wins, never a 500. Sets
Content-Type/Length/Last-Modified, honours HEAD and If-Modified-Since (304).
WithIndex / WithStripPrefix options. fasthttp owns the streamed file's close.

Middleware = func(Handler) Handler, Chain(mw...), and App.With(mw...) — chi's
per-route wrapping idiom. With wraps the leaf at registration (not via c.Next),
Chain composes left-to-right. Coexists with Use: Use = global/prefix stack
(declaration order), With/Chain = per-route explicit wrapping.

Tests: serves file (content/type/len) over embed.FS AND os.DirFS, HEAD,
traversal blocked, missing->Next->catch-all, specificity beats the wildcard,
index, strip-prefix, 304; Chain/With execution order + the cloud
rateLimit+CSRF order and short-circuit proof. Suite green except the two
pre-existing macOS-host failures (TestListen_DualTransport,
TestMCP_FreeToolSurface).
