feat(forge): migrate JavaScript experiments

[fronzec]

Closes #9

Summary

• Migrate all three javascript-projects snapshots into Forge's concept-first catalog.
• Add self-contained experiment records with exact verification evidence and known dependency risks.
• Restore the Express Generator server bootstrap that was missing from the source repository.

Changes

Area	Change
web-framework-basics/hello-world/node-express/	Add the minimal Express route and runtime snapshot.
application-scaffolding/express-generator/node-express/	Add the generated Express structure and restore bin/www.
rest-api/todo-service/node-express-sequelize/	Add the TODO API, Sequelize migration, Compose environment, and Jest setup test.
README.md	Add all three experiments to the Forge catalog.

Size Exception

The maintainer explicitly approved a single-PR size:exception. Of 10,838 added lines, 8,973 are generated source package-lock.json files and 1,156 are inherited .gitignore files. Splitting those snapshots would add lifecycle overhead without reducing semantic review scope.

Test Plan

• Ran git pull --ff-only origin main; source HEAD and origin/main match 1ba7330.
• Verified all non-adapted files against the source snapshots with checksum-aware rsync dry runs.
• Ran npm ci independently for all three experiments.
• Ran node --check over all migrated JavaScript.
• Started both standalone HTTP examples and checked their live root responses.
• Ran npm test -- --runInBand for TODO: 1 test and 1 suite passed.
• Ran shellcheck over run.sh and stop.sh.
• Run the TODO PostgreSQL boundary; local Podman 5.8.2 could not connect to its stopped machine.

Contributor Checklist

• Linked approved issue feat(forge): migrate JavaScript experiments #9.
• Used conventional commit format.
• Kept documentation with each experiment.
• Recorded dependency vulnerabilities instead of silently upgrading the historical snapshots.
• Added no AI attribution or co-author trailers.
