Pull request overview

Adds wildcard subpath exports to support per-function deep imports (e.g. es-toolkit/function/debounce) across the main groups, and updates build/test tooling to accommodate these new export patterns.

Changes:

• Add ./<group>/* wildcard entries to exports and publishConfig.exports for granular imports.
• Update Rollup entrypoint resolution to ignore wildcard export targets.
• Expand .attw.json entrypoint sampling for types validation.

@nunomarks does this handle compat namespace granular exports? I don’t see handling for that case, and original issue mentioned Lodash usage where a lot of compat functions usage come from.

Made that change, thank you, overlooked that. Please review when you can.

node10 does not support subpath exports. It is also very ancient, so I'm not sure you'd want to support it. For now I'm suggesting to ignore it. This profile field is only supported on the 0.17.x version of the attw CLI

@niksy can this be reviewed again ?

I think this looks OK, but final word should be from the maintainers.
