## Summary
- make Coder Agents available to organization members without a separate
built-in role
- remove the obsolete role from backend and frontend role surfaces
- update authorization, UI, documentation, and regression coverage
## Database note
This PR intentionally ships no migration so it backports cleanly across
diverged migration numbers. Stale `agents-access` grants may remain in
user role arrays and org default member roles; the retired name is
treated as a grant of nothing (role expansion drops it, assignment
validation ignores it, and the name stays reserved). A follow-up PR will
add the data cleanup migration.
## Validation
- `make gen`
- `make lint`
- repository pre-commit checks
- targeted RBAC, migration, chat API, enterprise, site, Storybook, and
race tests
- `git diff --check`
## Rollback note
Rolling back the deployment restores the previous behavior directly: no
data changed, and older binaries still resolve any lingering
`agents-access` grants.
