- The medicine database is now much bigger and has a real update path.

Added:
Live source updater for RxNorm, DailyMed, and openFDA.
Admin dashboard panel to refresh medicine sources.
CLI updater for periodic jobs: 
[scripts/update_medicine_catalog.php](/Users/tyemeclifford/Documents/GH/workout/scripts/update_medicine_catalog.php)
Update history table: medication_source_updates.
Curl fallback for external fetches when PHP stream DNS fails.
README instructions for periodic updates.
I also ran the imports:
Current medication catalog count: 6,002.
Latest source imports:RxNorm: 3,875 inserted, 1,125 updated.
openFDA: 912 inserted, 88 updated.
DailyMed: 95 inserted.

Periodic update command:
/Users/tyemeclifford/frankenphp php-cli 
scripts/update_medicine_catalog.php 5000 all

+## Medicine Catalog Updates
+
+The catalog ships with a curated starter set, the current SQLite file includes thousands of imported medicine concepts, and it can be refreshed from public medicine sources.
+
+From the admin dashboard, use the medicine source updater and choose `All sources`, `RxNorm`, `DailyMed`, or `openFDA`.
+
+From the command line:
+
+```sh
+/Users/tyemeclifford/frankenphp php-cli scripts/update_medicine_catalog.php 1000 all
+```
+
+For a periodic cron-style update, run the same command nightly or weekly. The first argument is the max rows per source, from `25` to `5000`; the second argument is `all`, `RxNorm`, `DailyMed`, or `openFDA`.
+
