Update: extension points are no longer declared by declare module augmentation (JSR rejects it in a published package). They are typed CapabilityKey<T> tokens instead; wherever this description says "declaration merging", read "typed key". Done in the slice-2 PR stacked on this one.

Part of duneorg/dune#127. Stacked on #5; pairs with the core contract-split PR.

BarAction* types and the bar.actions key live here; the transform reads ctx.capabilities (admin.prefix, bar.actions) instead of core-supplied fields.

Closing: this version declared the extension points with declare module, which JSR rejects (no-slow-types: ambient module). #7, stacked on this branch, replaces it with typed capability keys, so it is retargeted to feat/capabilities and review sees the typed-key version once. The branch feat/own-contributions is kept; nothing is lost.
