v1.3.0 — Quality Pass

This release is a focused quality pass with no new features. Every change is a bug fix or structural improvement discovered during a full code audit.

Sync Engine (`class-cctec-sync.php`)

Ticket/price data (fetch_ticket_data) is now only fetched on actual creates and updates — previously it fired an extra PCO API call on every event including unchanged ones, adding hundreds of unnecessary requests per day on active calendars
Signup name map is now cached between sync passes — previously re-fetched from PCO on every calendar-mode sync
find_post_by_meta() replaces two near-identical duplicate methods
delete_stale() now explicitly excludes already-trashed posts from its query — previously it would re-trash them on every sync, inflating the deleted count and writing unnecessary DB rows
Registration URL now correctly uses new_registration_url in the calendar-mode name-match path (the registrations-only path was already correct since v1.1.1)
Venue creation unified into a single get_or_create_venue_from_attrs() path used by both sync modes
no_found_rows => true added to all get_posts() queries to skip unnecessary SQL COUNT
Dead code block removed from recurring instance handling
run() split into run_registrations() and run_calendar() for clarity

Old featured image is now only deleted after the new download succeeds — previously a failed sideload would wipe the existing image with nothing to replace it

Auto-injected button is now suppressed when [pco_register] is already present in the page content — previously both would render, producing two buttons
All three button render paths ([pco_register], [pco_event_card], auto-inject) now share a single default_label() method that reads the cctec_register_label option — previously the event card ignored this setting
CSS enqueue check replaced tribe_is_event() with is_singular('tribe_events') for reliability across all themes

cctec_delete_removed and cctec_register_label were never seeded on activation — fresh installs had no stored value, causing get_option() to return false. All 10 plugin options now use add_option() in activate(), which is a no-op on upgrades so existing settings are never overwritten
Custom cron interval cctec_every_6_hours moved from admin_init to a top-level add_filter('cron_schedules') — WP requires the interval to be registered on every load, not just in the admin, for scheduled events to fire correctly

Drop-in replacement — no database changes, no settings reset. Existing synced events are unaffected.
