Record, milestone, phase and plan citations go from every migration header;
the "end before start" fix (0043) and the suppressed-count column (0095)
state the condition they prevent rather than the incident. 0053 and 0055
pointed at design specs under docs/superpowers that are not in the repo;
those pointers are removed.
Kept: alembic's generated "Create Date:" headers (template metadata, not
rationale), 0121's ARM_BORN justification beside the constant, and 0051's
illustrative "update task 42" format example.

The column becomes token_sealed (migration 0122 seals existing rows with a
frozen copy of the v1 key), every reader opens it through connection_token,
a row this instance cannot open is skipped with a warning, and Settings asks
for that token again.
