New modules:
- server/mailer.mjs: nodemailer transport wrapper
- server/mail_perms.mjs: runtime permission store, persisted to disk
New actions:
- send-email: checks (caller, to, topic) permission before sending
- set-mail-permission: grant/revoke permissions, gated by canApprove
- get-mail-permissions: list current permissions
Handler signature extended to handler(params, ctx) where ctx carries
caller, users, mail_perm_store and mailer_send. Existing handlers
ignore ctx so the change is backwards-compatible.
SMTP config lives in secrets.json under optional 'smtp' key.
Mail permissions path via --mail-perms or CONDUIT_MAIL_PERMS.

Each request is signed with HMAC-SHA256 over timestamp+body using a
per-user secret loaded from a --secrets file (never env vars or git).
Users have a canApprove list controlling who may approve queued actions.
Queue entries track submitted_by for permission checks on approve/deny.
Also renames all identifiers to snake_case throughout the codebase.
