Feat/lesson 25 hw toby evans

[tobyev]

I completed my Lesson 25 homework by adding a new SQL queries file (lesson_25/db/db_app/src/main/resources/queries/lesson25_toby_evans.sql),
creating a library_users table with seeded users in the SQLite DB, implementing LibraryUserModel and LibraryUserRepository, and wiring users into the LibraryDataModel via LibraryDbDataLoader .I confirmed the project builds and runs with ./gradlew :db_app:run, and all changes were staged, committed, pushed, and are ready for review on the branch feat/lesson-25-hw-toby-evans.

Problem area(s):

• Targeting the wrong module path ( db/...) instead of the correct lesson_25/db/...
• Heredoc creation hiccup (file wasn't created until the closing EOF was on its own line)
• SQLite "unable to open database file" due to using the wrong DB path
• Not finding the Gradle wrapper at repo root (needed to run from lesson_25/db)
• sed insertion didn't match return dataModel; on first try (regex tweak required)

Lessons learned:

• Verify module paths before creating/moving files; prefer lesson_25/db/db_app/...
• When using heredocs, ensure the final line is exactly EOF with no extra spaces
• Always run SQLite against the actual DB file ( lesson_25/.../sqlite/data.db ) and verify with .schema
• Run Gradle from the module that contains the wrapper (lesson_25/db/gradlew )
• Use grep checks before/after automated edits and confirm with a rebuild/run
