Bundles each entry point as ESM with esbuild's splitting:true so
shared transitive dependencies (Azure storage, undici, octokit, ...)
live in shared chunk files under lib/chunks/ instead of being
duplicated into every entry bundle.
A small banner is injected so bundled CommonJS deps that call
require(), __filename or __dirname at runtime still work. A
lib/package.json with { "type": "module" } is written by the build
so the bundles can keep the .js extension while being loaded as ESM
by Node; this scope avoids touching the tsc output in build/ and the
action.yml entrypoints stay unchanged.
On a measured tar.gz of the working tree this takes the repo from
~9.5 MB to ~2.6 MB compressed (lib/ alone: 8.0 MB -> 0.7 MB).
