chore: remove declarationMap and restrict published files

[sv2dev]

Summary

• Remove declarationMap: true from root tsconfig.json — declaration maps are not needed for consumers
• Add files field to both esroute and @esroute/lit packages to only publish dist/, LICENSE, and README.md, excluding tsconfig.check.json, tsconfig.tsbuildinfo, and source files

Test plan

• Run npm run build and confirm no .d.ts.map files in dist/
• Run npm pack --dry-run in each package and confirm only dist/, LICENSE, and README.md are included

Summary by CodeRabbit

• Chores
  • Optimized published packages to include only essential files (distribution, license, and documentation), reducing download size and improving installation efficiency
  • Refined TypeScript build configuration for streamlined compilation

Walkthrough

The changes update build and publication configuration for the monorepo. Two package.json files now explicitly specify publishable contents, and the TypeScript configuration disables declaration map generation during compilation.

Changes

Cohort / File(s)	Summary
Package Publication Configuration packages/esroute-lit/package.json, packages/esroute/package.json	Added files field to restrict published package contents to dist, LICENSE, and README.md.
TypeScript Build Configuration tsconfig.json	Removed declarationMap: true option, disabling generation of declaration map files for TypeScript declarations.

Poem

🐰 Hops through the config with glee,
Files now lean, trim, and light,
Maps removed, declarations pure,
Packages published just right!
