Replace stub wallet keypair with real Phantom sign-in

Auth now goes through an actual connected Solana wallet instead of a
locally-generated ed25519 keypair. Phantom's window.solana provider
is only reachable from a page's own JS world, not an isolated-world
content script, so this adds a second world:'MAIN' content script
(wallet-bridge.content.ts + wallet-bridge/inject.ts) that talks to
window.solana directly and relays to the isolated world via window
CustomEvents (wallet-bridge/relay.ts), matched by request id.

wallet-connect.ts orchestrates: try a silent onlyIfTrusted connect on
load; if that fails, show an on-page banner (wallet-bridge/banner.ts)
whose click handler is what actually calls connect() -- Phantom
requires a real user gesture for the approval popup on a first-ever
connect, which a click relayed from the extension popup wouldn't
count as by the time it reaches the wallet.

background/wallet-auth.ts runs the REST auth flow (nonce -> ask the
tab's content script to sign it -> verify -> store session token)
once a wallet reports connected. ws-client.ts no longer force-retries
with a known-bad token on auth failure; it calls onAuthExpired
instead (which clears the token and prompts a silent wallet
reconnect) and exposes reconnectNow() so background.ts can
short-circuit the backoff wait once a fresh token exists.

identity.ts and its tweetnacl dependency are gone -- no more stub
signer.

Untested against real Phantom (no browser automation available this
session) -- flagged in CLAUDE.md as needing manual verification,
along with a note that world:'MAIN' needs Firefox 128+.
