chore: Address issues with /*#__PURE__*/ annotations placed inside parens cause Rolldown/Vite 8

[nev21]

• address issues with /#PURE/ annotations placed inside parens cause Rolldown/Vite 8 [INVALID_ANNOTATION] warnings and disable tree-shaking
• add a generated-artifact validation script at bundle-pure-annotations-check.js to scan packaged JavaScript under bundle and dist outputs
• fail when PURE annotations have whitespace after opening parenthesis, and report file plus line for quick diagnosis
• add progress logging to show discovered files and each file being processed
• run the new validation as part of size-check in package.json
• widen the PURE annotation normalization spacing matcher in rollup.config.js to tolerate larger whitespace ranges before rewriting to canonical form

Pull request overview

Addresses Rolldown/Vite 8 [INVALID_ANNOTATION] warnings caused by /*#__PURE__*/ annotations emitted with whitespace between the opening paren and the comment, which disables tree-shaking. Adds a rollup plugin to normalize emitted annotations and a post-build validation script.

Changes:

• Add fixPureAnnotations rollup plugin (using magic-string) that rewrites spaced PURE annotations to the canonical (/*#__PURE__*/ form across all rollup configs.
• Add lib/test/bundle-pure-annotations-check.js to scan lib/bundle and lib/dist .js outputs for invalid annotations and fail the build with file:line diagnostics.
• Wire the new check into the size-check npm script.
