Pull request overview
This PR aims to fix failures when re-editing/viewing an existing Teams meeting link after Moodle/Tiny re-saves the HTML and changes the percent-encoding case, by making URL hashing stable across %xx case differences and migrating existing stored hashes accordingly.
Changes:
- Normalises
%xxpercent-encoding to uppercase before hashing meeting URLs (with a fallback lookup for legacy lowercase-hash rows). - Adds an upgrade step intended to recompute
link/linkhashusing the normalised URL form. - Bumps the plugin version to trigger the upgrade step.
