"+ Add channel" jumped straight into a generic Name+Secret form, so the
"hashtag channel" convention documented in docs/companion_protocol.md
(secret = first 16 bytes of sha256("#topic")) was only reachable by
already knowing to type a literal "#topic" into the passphrase field --
nothing in the UI surfaced it. The phone app instead shows an explicit
channel-type picker; this adds the same on-device.
"+ Add channel" now asks Public / Hashtag / Private first:
- Public commits immediately with the well-known default channel's name
and secret (8b3387e9c5cdea6ac9e5edbaa115cd72, confirmed to match
MyMesh.cpp's PUBLIC_GROUP_PSK and the docs' published key) -- useful
to restore it if deleted.
- Hashtag shows a single Topic field; Save synthesizes name="#topic" and
derives the secret via the existing SHA-256 passphrase path -- same
underlying mechanism Private already had, just discoverable without
knowing the "#" convention.
- Private is today's manual Name+Secret form, unchanged.
Editing an existing channel skips the picker (no ambiguity to resolve
there). Extracted hexToSecret() out of deriveSecret()'s hex-mode branch
so Public's fixed key parses through the same code instead of a second
hand-rolled loop. No other file needed changes -- openAdd()/openEdit()/
active()/render()/handleInput() keep their existing signatures.
