[marketplace] fix skill shadowed by command + discover-first routing (#107)

* feat(marketplace): discover-first commerce routing + provisioning guidance

Make the model reliably reach for the Marketplace when an app needs an
external service, instead of hardcoding a provider from memory.

- knowledge-update (always-injected at session start): add a discover-first
  directive — load the `marketplace` skill, then discover + provision a real
  integration BEFORE planning/writing code/asking.
- marketplace SKILL.md: broaden the description (commerce/payments/etc. as the
  catch-all for capabilities without a dedicated skill); restructure into
  discover -> install -> build with an anti-mock/anti-punt rule; add a
  Recommendations section keyed on the product-catalog test (commerce vs
  payments), with no hardcoded providers (discover names them).

* fix(marketplace): remove command that shadowed the skill; tighten routing

The `marketplace` skill and `/marketplace` command shared a name, so the
command shadowed the skill — Skill(vercel:marketplace) loaded the command's
runbook instead, and the skill's routing guidance never reached the model.

Remove the command (marketplace is skill-only, like the other capabilities)
so the skill loads, and tighten routing: discover-first flow, a preferred-
provider table (commerce -> Shopify, payments -> Stripe), and a slimmer
knowledge-update that points at the skill.

* chore(release): patch-bump plugin manifests to 0.45.1

Backwards-compatible fix (marketplace skill routing); bump the version in
all three shipped manifests (.claude-plugin, .cursor-plugin, .plugin).
