- Scope WebSocket auth bypass to only WS endpoints by restructuring
routes into separate chi Groups. Non-WS routes no longer passthrough
unauthenticated requests with spoofed Upgrade headers. Added
optionalAPIKeyOrJWT middleware for WS routes (injects auth context
from API key/JWT if present, passes through otherwise) and
markAdminWS middleware for admin WS routes.
- Fix nil pointer dereference in envd Handler.Wait() — p.tty.Close()
was called unconditionally but p.tty is nil for non-PTY processes,
crashing every non-PTY process exit.
- Fix goroutine leak in sandbox Pause — stopSampler was never called,
leaking one sampler goroutine per successful pause operation.
- Decouple PTY WebSocket reads from RPC dispatch using a buffered
channel to prevent backpressure-induced connection drops under fast
typing. Includes input coalescing to reduce RPC call volume.
Extracts Mailer interface, EmailData, and Button to pkg/email/types.go
so the cloud repo can use them via ServerContext. internal/email re-exports
the types as aliases so existing callers are unchanged. Also fixes
pre-existing lint errors (unchecked rollback and deadline calls).
