Local Dev 5e27a1b53d hermes: phone discovery (opt-in), lookup contacts by number
Users can link one or more phone numbers to their Hermes identity by
publishing a kind:30078 claim event whose d-tag is a SHA-256 hash of the
E.164 number. The number itself never leaves the device. Add-contact and
message-send now also accept a +phone input directly — the client hashes it
and queries relays for the matching Hermes identity.

- lib/hermes.js: normalisePhone(str) strips separators + a leading 00
  into E.164, rejects anything that doesn't fit +[country][7-15 digits].
  hashPhone(str) → base64url-truncated-to-32 SHA-256 digest, used as the
  d-tag suffix under PHONE_DTAG_PREFIX. buildPhoneClaimEvent /
  buildPhoneRetractEvent emit the signed kind:30078 / NIP-09 kind:5.
- main.js: _hermesAPI.getPhone / setPhone / clearPhone / findByPhones.
  Plaintext phone persists in the identity meta (locally only) so the
  user can see what's linked and retract it; event ids are kept so a
  retract can reference the exact wire event. hermesResolveTo takes a
  phone-shaped input and does the discovery lookup transparently, so
  contactsAdd and send accept phones without a new entry point.
- panel.html: Settings → Phone discovery (link / unlink + privacy note),
  add-contact placeholder now lists +phone alongside the other forms.

Privacy stance stated in the UI: "anyone who already knows your number
can find you — same tradeoff as number-based messengers." No PSI tricks
yet; plain hash. Users who don't want it just don't link, which is the
default. Future slice can add a pepper if operators want to narrow the
brute-force window.

// Hermes bundled add-on — thin proxy to the host's panel API.
//
// All the real messaging code (NIP-17 wrap/unwrap, relay subscriptions,
// persistent inbox, contacts) lives in Theseus main.js. Too much raw network
// + crypto to run under the add-on sandbox, and the vault seed must never
// cross the host/add-on boundary.
//
// This file does two things:
// 1. Register the left-strip sidebar entry (so Hermes is discoverable
// without pressing Ctrl+Shift+E).
// 2. Proxy a small, allow-listed set of panel operations between the
// panel's silentmode.invoke() calls and main.js's `global._hermesAPI`.
// The panel never sees ipcRenderer — only this named handler surface.
//
// Events coming the other way (inbox updates, relay status changes) are
// fanned out via a shared ipcMain event bus `__hermes_bus`: main.js's
// hermesBusEmit publishes, this file forwards each payload to the panel.
