/**
|
|
* Signal — via bbernhard/signal-cli-rest-api
|
|
* (https://github.com/bbernhard/signal-cli-rest-api).
|
|
*
|
|
* Supported formats:
|
|
* signal://host[:port]/+source/+target1[/+target2/...]
|
|
* signals://host[:port]/+source/+target1[/+target2/...] (HTTPS)
|
|
*
|
|
* `+source` is the sender's registered Signal number (E.164 format). The '+'
|
|
* is optional in the URL — we re-add it. Recipients can be Signal phone
|
|
* numbers (numeric, '+' gets added) or group IDs (signal-cli's "group.<base64>"
|
|
* form, passed through untouched).
|
