Subject: [PATCH] Update zoneinfo files to 2026b

British Columbia (America/Vancouver, and its link Canada/Pacific)
moved to permanent -07 on 2026-03-09 (although the source change
was temporarily set to occur on 2026-11-01 instead, when it first
makes a difference).

zic now identifies when one zone abbreviation is a suffix of
another, allowing them to share table space.  This saves 4 bytes
in Asia/Ho_Chi_Minh (and its link Asia/Saigon), Asia/Phnom_Penh,
and Asia/Vientiane.
