Node 26.12.1 (CVE-2026-105481) makes the http agent check a kept-alive
socket for pending data before reusing it. The queued request now sees
the server's EOF, opens a new connection to the closed server and gets
ECONNREFUSED instead of ECONNRESET. Either way the request is dropped.

Migrate the usage of CommonJS specific code and imports to ESM. Roughly
summarised this:
- Changes all require() calls to import statement or expressions.
- Changes usage of module.exports to export statements.
- Replaces require.resolve with import.meta.resolve.
- Replaces conditional imports with conditional subpath imports.
- Replaces module === require.main with import.meta.main.
- Adds the full filename with extention to all relative imports.
- Changes all usage of __dirname and __filename to their import.meta
equivalents.
- Sets "type": "module" in package.json files.
- Removes usage of "use strict".
- Adds .ts an an alias of .js for the webpack build.
Due to differences in how require and import resolves files the plugin
entrypoints will have to include the filename and extension after this
migration in order to work.
These packages are obsoleted by the promises API to the built-in Node fs
module. The fs-extra package is also causing problems with broken APIs
that don't behave the same as Node's fs module, and throwing errors
without code properties on them.
Use a separate folder for the TypeScript build for Node.js in the dist
folder. This makes each type of build consistently have its own output
folder instead of being interleaved with the Node.js build.
Move all functions and classes currently available through lib/name and
libName to be under a single flat namespace in lib. This make
reorganising the lib namespace much simpler as the location of symbols
can move without breaking the consumers of lib.
The multi-entrypoint design was already problematic for the web plugin
system which couldn't effectively use it due to how webpack's shared
module system is awkward to set up with multiple entrypoints per package.
The role of the master server as the party controlling every part of the
cluster is not well reflected in its name and has caused confusion among
users on several occasions. Rename master to controller to better
reflects its role.
