Introduce cmdcore.CommandSpec as the single typed leaf definition and
cmdcore.NewCommand as the one orchestration path (flags → constraint decl
checks → Runtime Schema projection → constraint help → PostMount → RunE
escape / generated RunE{required → constraints → Validate → BuildArgs →
ConfirmRisk → Dispatch}). Dispatch becomes a spec property, not a
separate framework.
helpers.NewLeafCommand now delegates to cmdcore.NewCommand(FromLeafSpec),
so every LeafSpec command — including all 27 devapp leaves — flows through
the unified spec. The MCP dispatch (Call / callMCPToolOnServer /
callMCPTool) is captured in the FromLeafSpec closure.
internal/shortcut/adapter.go adds FromShortcut, the typed seam mapping a
Shortcut's shared base (flags of every kind, known constraints, risk,
help identity) into a CommandSpec. It is intentionally NOT wired into the
live mount() path: Shortcut's multi-step Execute, decline-returns-nil
semantics, and Flag.Enum/Hidden/custom-constraint extras are not modeled
by cmdcore yet, so the 376 shipped shortcuts stay byte-identical. Live
wiring is deferred to Phase 3, gated by shortcut-list + schema equivalence.
Commands are provably unaffected: check-generated-drift ok (840 tools,
identical hashes), `dws schema --all` and `shortcut list` unchanged, full
helpers/cmdcore/shortcut suites green, changed-code coverage 100%.
