GL-2: --mode appliance|byo install profile (host-install v1.10.0) + harness

Mandatory install profile (no default): byo = a host the operator does not
own. Break-glass gated OFF at its call site in byo (root@pam never touched),
mandatory --cores/--memory, argv-time refusals (--enable-oob/--rotate-recovery,
non-9.x PVE, missing --acl-storages), host-mutation disclosure + typed-hostname
ack, byo config asserts (lan_resolver/wg_tunnel/oob off; byo flips the
lan_resolver write default to off), pool+ACL verify asserts in BOTH modes (R2),
--preflight-only (no state, PASS/FAIL verdict), resume mode-mismatch refusal,
FELHOM_INSTALL_STATE_DIR harness override.

NEW scripts/hostinstall-mode-harness.sh: static refusal matrix C1-C4 + grep
invariants + PVE tier (C5 + A/B dry transcripts). 16/16 PASS on felhom-pve
(C5 live); red-proofs RP-1..RP-3 run->fail->revert. shellcheck clean at
severity=warning. Docs: day0-install SC.5 byo section + trust model; REUSE row;
CONTEXT + REPORT. Live drill = GL-6 (supervised); STOP honored (no non-dry run).
