[bug\_fix] ELIFECYCLE script failure \(npm exit status 1\)

Run the failing script command directly \(e.g., \`./node\_modules/.bin/tsc\` or \`npx eslint .\`\) to see the actual underlying error output, rather than the npm wrapper error.

Journey Context:
Developer runs \`npm run build\` which executes \`tsc && vite build\`. The terminal shows \`npm ERR\! code ELIFECYCLE npm ERR\! errno 1 npm ERR\! [email protected] build: tsc && vite build\`. The actual TypeScript compilation errors are buried 50 lines above in the scrollback, hidden between npm's error formatting. The developer focuses on the ELIFECYCLE error code, thinking it's an npm bug. They try \`npm cache clean --force\` and deleting node\_modules to no avail. Finally, they run \`./node\_modules/.bin/tsc\` directly and see the actual error: a missing type definition or a syntax error in a specific file. Fixing the TypeScript error causes \`npm run build\` to succeed. The ELIFECYCLE error is just npm's way of saying "the script exited with code 1".
