tzdata/tzcode-native: upgrade 2026a -> 2026b

The 2026b release contains the following changes:

Briefly:
    British Columbia moved to permanent -07 on 2026-03-09.
    Some more overflow bugs have been fixed in zic.

Changes to future timestamps

    British Columbia’s 2026-03-08 spring forward was its last
    foreseeable clock change, as it moved to permanent -07 thereafter.
    (Thanks to Arthur David Olson.)  Although the change to permanent
    -07 legally took place on 2026-03-09, temporarily model the change
    to occur on 2026-11-01 at 02:00 instead.  This works around a
    limitation in CLDR v48.2 (2026-03-17).  This temporary hack is
    planned to be removed after CLDR is fixed.

Changes to code

    zic no longer mishandles a last transition to a new time type.
    zic no longer overflows a buffer when generating a TZ string like
    "PST-167:59:58PDT-167:59:59,M11.5.6/-167:59:59,M12.5.6/-167:59:59",
    which can occur with adversarial input.  (Thanks to Naveed Khan.)

    zic no longer generates a longer TZif file than necessary when
    an earlier time zone abbreviation is a suffix of a later one.
    As a nice side effect, zic no longer overflows a buffer when given
    a long series of abbreviations, each a suffix of the next.
    (Buffer overflow reported by Arthur Chan.)

    zic no longer overflows an int when processing input like ‘Zone
    Ouch 2147483648:00:00 - LMT’.  The int overflow can lead to buffer
    overflow in adversarial cases.  (Thanks to Naveed Khan.)

    zic now checks for signals more often.
