feat(ttl): Gate Script A on bcmcmd port-up count, not thermal sensors

wait_init.ttl V2.0.0 now polls

    bcmcmd -n 0 -c ps | grep -w up | wc -l
    bcmcmd -n 1 -c ps | grep -w up | wc -l

and proceeds only when BOTH exceed 216, so the baseline is taken with
the data plane actually up rather than merely with pmon answering.

V1.0.0 could use `wait "Thermal Not detected" prompt` because that was a
string-presence test. Comparing a count needs the value captured, so the
count is wrapped in an echo marker and read with waitregex +
groupmatchstr1 + str2int. The command echo cannot false-match: it reads
"PORTS0=$(bcmcmd ..." and the pattern requires a digit immediately after
the "=". The optional-space allowance covers a wc that pads its output.

The two thresholds are compared in nested ifs rather than with `and`,
which is bitwise in TTL.

WT_MIN and WT_INTERVAL are at the top of the file. The enter/exit prompt
contract is unchanged, so Script A's surrounding waits still line up.
Script A -> V1.0.4.
