Teknium 706f33d424 feat(update): sibling profiles' configs migrate with the fleet — no more silent version drift (#20438/#54926/#79048)
The shared checkout serves every profile, but hermes update migrated
only the active profile's config.yaml. Siblings kept their old
_config_version until their (correctly restarted, post-#91378) gateway
hit a config shape the new code couldn't read — the last unabsorbed
substance from the Phase-2 restart-swarm audit (#20438 earliest, 2026
field repro on #79048: sibling at v33 vs v37).

_migrate_sibling_profile_configs(): per sibling home, scope config
reads/writes via the context-local HERMES_HOME override (ContextVar —
never os.environ), check version, run the NON-INTERACTIVE safe
migration; prompt-requiring settings stay for the profile's own next
interactive session (same contract as gateway-mode). Broken profiles
are skipped without blocking the sweep; override always reset.

Sabotage-verified; live E2E in a fresh process with real drifted
config files: v12→v38 and v25→v38 on disk, provider preserved, the
documented #81946 personality-reset migration correctly applied to
siblings too, never-configured profile untouched, active home
untouched, second run idempotent.
