The ctx.pear surface exposes selected Pear and Bare build/bundling packages
(pear-build, pear-bundle, bare-bundle-compile, etc.) when BARE_OS_BARE_MODULES
is enabled.
pear stage writes a deployment tree under <project>/.pear/stage/:
package.json, sources/**, stage.json, and app.bundle.js when packing succeeds.
pear release publishes the staged tree to a writable HDMS Hyperdrive and prints
pear:// links (requires logged-in identity + HDMS). pear seed keeps the release
drive replicating on Hyperswarm.
Use the pear-dev agent skill together with the appstore skill for
autonomous "build Pear app → publish to my store" workflows.
