kevinveenbirkenbachandClaude Opus 4.7 90ef6b9269 feat(env): auto-detect INFINITO_OUTER_NETWORK_MTU from host default route ...

`make dotenv` previously copied the static 1500 default from
env/default.env into .env for the compose bridge MTU, regardless of the
host's actual outbound MTU. On hosts where the default-route interface
sits below 1500 (VPN, tunnels, jumbo-frame negotiation failure) the
bridge ended up larger than the path MTU and TLS handshakes silently
lost their ServerHello fragments — every dotenv regeneration without
an explicit INFINITO_OUTER_NETWORK_MTU= override silently re-introduced
the regression.

Replaces the static-passthrough entry with a dedicated handler that
walks /proc/net/route to find the default-route interface, reads
/sys/class/net/<iface>/mtu, and seeds the value via setdefault so any
caller-set env still wins. Falls back to the env/default.env static
default when detection cannot complete (no default route, unreadable
sysfs entry, foreign host layout).

Adds 13 unit tests covering the /proc parse, the sysfs read, the
composition, and the handler's apply contract (detected wins,
static fallback, no-op when both empty, caller-env override).
