Subject: [PATCH] :sparkles: Extend tsconfig from @tsconfig/node26 and
 @tsconfig/strictest

- Replace hand-rolled strict flags with @tsconfig/strictest
- Pick up Node 26 module/lib/target from @tsconfig/node26
- Add exactOptionalPropertyTypes (the main strictness gain)
- Pin target to es2024 to remain conservative for the published build
