Michał Pierzchała b19ee116b5 fix(remote): stop persisting the daemon bearer token, and authenticate forced-reconnect release correctly (#1648)
* fix(remote): stop persisting the daemon bearer token in connection state

ADR 0007 requires generated connection profiles to strip daemon and Metro
bearer tokens; only the Metro half was honored. `connect` was writing the
daemon bearer token into the 0600 connection-state file, and every later
command read it back out.

Stop writing `authToken` into `RemoteConnectionState['daemon']` and resolve
it at each reader from the existing flag -> environment
(AGENT_DEVICE_DAEMON_AUTH_TOKEN) -> remote-config-profile chain instead,
matching src/cli/auth-session.ts's precedence.

Behavior change: a user who ran `connect --daemon-auth-token <value>` and
relied on later commands picking the token back up from the state file will
now get an auth failure. They must export AGENT_DEVICE_DAEMON_AUTH_TOKEN,
set daemonAuthToken in their remote config, or pass --daemon-auth-token on
each command. website/docs/docs/remote-proxy.md is updated to show the
supported env-var workflow.

* fix(remote): authenticate forced-reconnect lease release with the previous endpoint's own credential

connect --force released the previous connection's lease using the new
connection's ambient daemonAuthToken instead of the previous endpoint's own
credential, and swallowed the resulting auth failure — silently orphaning the
old lease when replacing a connection with a differently-authenticated one.

Resolve the release token from the previous connection's own remote-config
profile first, fall back to the ambient token only when the two connections
share the same daemon endpoint, and otherwise skip the release and surface an
actionable notice (tenant, run id, lease id, endpoint) through the existing
connect notice channel instead of hiding the failure.

* fix(remote): stop merging ambient env defaults into the previous lease's own token

resolvePreviousOwnDaemonAuthToken read the previous connection's profile
through resolveRemoteConfigProfile, which folds AGENT_DEVICE_DAEMON_AUTH_TOKEN
(and other env defaults) into the result. When the previous config file
declared no token and the new connection's credential came from that same
global env var, it was misclassified as belonging to the previous endpoint
and sent there on forced-reconnect release — recreating the credential leak
the prior fix was meant to close, just via env instead of --daemon-auth-token.

Read the previous profile with the new readRemoteConfigFile (a provenance-
preserving, file-only load with no ambient env/CLI merging), so only a token
the previous config file itself declares can satisfy rule 1. Rules 2 and 3
are unchanged.

* fix(remote): verify the previous config file still speaks for its endpoint

Rule 1 reads the previous connection's own config file to recover a credential
that provably belongs to the previous endpoint. It re-read
`previous.remoteConfigPath` and trusted whatever token that file holds *now* —
but a config path is routinely reused, so "connect to A from ./remote.json,
re-point ./remote.json at B, connect --force" classified B's token as A's own
and sent it to A during lease release. Same cross-endpoint leak the env-merge
fix closed, arriving through the file instead of the environment.

The file must now still vouch for the previous endpoint, by either of two
independent facts: its bytes still hash to the `remoteConfigHash` recorded at
connect time (so it is literally the declaration that stood up the previous
connection), or — if it changed — it still declares the same daemon base URL.
The second is what keeps an ordinary credential rotation releasing its lease
instead of orphaning one; endpoint equality, not the fact of an edit, is what
separates rotation from re-pointing.

Endpoint comparison runs both sides through `buildRemoteConnectionDaemonState`,
the same normalizer that produced the stored `daemon.baseUrl`.
