"""Add 'pr_reviewer' to the postgres agentrole enum.
|
||
|
|
|
||
|
|
The PR reviewer (``Role.PR_REVIEWER`` in foundation/identity) is a read-only
|
||
|
|
agent that reviews inbound external/fork PRs. Seeding/spawning its agent row
|
||
|
|
requires the postgres ``agentrole`` enum to carry the value. Mirrors migration
|
||
|
|
034's pattern.
