serveSpecializedNoSlash now consults zddc.ViewAt(dir, "dir"): an explicit
`views.dir` in the cascade overrides the default_tool-derived app for the
no-slash directory URL. default_tool stays the sugar fallback (ViewAt returns
it when no views.dir is declared), so existing deployments are unaffected —
purely additive.
Also fixes the mergeOverlay trap (per the .zddc-policy-key checklist): added
Views to walker.go's per-level merge so views: survives cascade resolution at
default-driven paths (without it the key silently no-ops). Verified by a
defaults-path unit test (TestViewAt): default_tool/dir_tool surface via ViewAt;
an explicit views: entry overrides default_tool and declares a file shape.
go build + go test ./... all green. (Next: ServeView config injection from
.zddc.d/, the file→form shape, recognizer retirement, client + ./build.)
