Service compose and .env content was sent inline in the SSH command.
Linux limits one argument to 128 KiB, so a service with a generated
compose over about 96 KB failed to save or start with "Argument list
too long".
- Add instant_remote_write_file(), which streams content to a remote
tee over SSH stdin (sudo tee for non-root SSH users)
- Add SshMultiplexingHelper::generateSshStdinCommand() with the same
SSH options as generateSshCommand()
- Write the service compose and .env with the new helper
Allow validated host file and directory mounts outside resource directories
while protecting external paths from deletion.
Clean up cancelled deployment containers and clear tracked process IDs.
Preserve legacy KeyDB and Dragonfly password parsing, accept server backup
paths without extension restrictions, and allow Compose variable proxy ports.
- Write remote secret values as exact dotenv literals in the service .env
file and escape "$" where they go directly into a generated compose file
(environment, start commands, healthchecks).
- Resolve remote secrets before a service or database restart stops the
running resource, and show the secret manager error instead of a generic
start failure (new RemoteSecretException).
- Cache fetched key names for the autocomplete and rate limit how often a
user can contact the secret manager.
