etwenandClaude Opus 5 fedf697977 docs(margin): Realign channel-pairing comments with bench wiring
The values were corrected in ababb2c but every comment describing the
pairing still said the old one, leaving four confs where the comment
contradicted the line it sat on:

    CB_I2C_CH=8           # CB F3 Ch6 = SWB0 CONN13/CONN14 ...

That reads as a typo waiting to be "fixed" back to 6, which would undo
a bench-verified value. Comments now state the real pairing:

    Ch6 = SWB0 CONN14/CONN16    Ch8 = SWB0 CONN13/CONN15
    Ch7 = SWB1 CONN14/CONN16    Ch9 = SWB1 CONN13/CONN15

Same map corrected in margin.sh's header (two places).

Ref/margin_command_trace.md gets a staleness banner rather than an
edit. Its 1223 expanded cb_pmbus_* commands were generated from the old
values - 487 of them use addresses that no longer exist (0x5D, 0x5F,
0x63, 0x65) - so patching the headings would leave the bodies wrong and
look authoritative. The banner carries the correct table and says the
SWB chapters need regenerating; chapters 1-4 are transport-independent
and remain valid.

Comments only: no CB_I2C_CH value and no CHIPS address was touched.
