      fix route-health: bulk route flush + wider health window · 5f8a5bc3
      Vitaly Lipatov authored 
      flush_gw_routes() deleted routes one-by-one in a loop (ip route del x127k),
which hung the oneshot service for 20+ minutes under netlink contention and
froze ALL gateway health monitoring. Replace with a single kernel-level
"ip route flush table T via GW" -- the same idiom route-update.sh already uses
for stale-gateway cleanup -- guarded by timeout 60.

Also widen the ping and vpn_status InfluxDB query windows from 1m to 3m. The
queries use last(), so a wider window does not delay reaction to a real outage;
it only stops an empty result (=> false "dead") when telegraf momentarily
starves under load. Together both changes break the flush->load->stale->flush
feedback loop.

Verified on igw: cycle time ~18s (was 20+ min), table 202 v6 routes via the
ikev2.vdska peer restored to 127259.

      route-health: check ikev2.fr/ikev2.gr by ping (no iperf3 server on peer) · 08365b47
      Vitaly Lipatov authored 
      These tunnel gateways had no iperf3 server / VPN-status feed on the remote
peer (rpi), so route-health judged them by iperf3 -> success=0 -> permanently
'down', masking real tunnel outages (a 7-day SA-down went unnoticed).

Add is_pingonly_gw() (ikev2.fr, ikev2.gr) and judge them by ping loss alone
(loss>=50 or no data = dead). Suppress the iperf/vpn marks in group display
and health.json output for ping-only gateways so a healthy gw no longer shows
'iperf=FAIL'.

      route-update: support explicit per-group pref override via options · 592e5f2d
      Vitaly Lipatov authored 
      ip rule pref is otherwise derived from alphabetical group order, so a group
cannot be consulted before a lexicographically-earlier one (e.g. fr vs egw)
without renaming it — and digits sort after letters in ru_RU.UTF-8, so even
a '0-fr' rename goes the wrong way.

Allow an options line "pref N" to set the group's pref base directly,
independent of name or locale. Used on fr (pref 900) so claude.ai via fr
wins over the egw/ai table (pref 1210).

Also call _fixup_rule_pref on the "resolved unchanged" skip path, so an
options-only change actually migrates the ip rule to the new pref (previously
the rule kept its old pref because load was skipped).

      route-update: support route-type keywords (blackhole/unreachable/...) in gateway · a7a51ff4
      Vitaly Lipatov authored 
      Allow a group's gateway file to contain a kernel route-type keyword
(blackhole/unreachable/prohibit/throw) instead of a next-hop. The script
then installs routes of that type (ip route replace <kw> <dst> table N),
so packets are rejected/dropped by the kernel instead of forwarded.

unreachable/prohibit return ICMP to the client, giving instant failure
(curl drops in ~2ms) vs hanging on a dead tunnel.

Used on routes6.d/fr where the France egress (ikev2.fr) is IPv4-only and
no IPv6 path exists: claude.ai AAAA now fast-rejects instead of timing out.

      route-update: prune stale volatile_ips for domains removed from lists · 3b1e5c99
      Vitaly Lipatov authored 
      expand_volatile_subnets() iterated the whole volatile_ips/ directory and
re-resolved every saved entry as a domain, never removing ones whose domain
was no longer in the .list. As a result, a domain removed from a list kept
re-injecting its (stale) IPs into the table forever — on igw this had
accumulated ~40 stale domains in web-bypass plus claude.ai/anthropic in ai,
shadowing the dedicated fr/claude.ai group.

Pass the current list file to expand_volatile_subnets and prune volatile_ips
entries whose domain is absent from the list before resolving.

      route-update: flush table when .list moves between groups · 41bffb6b
      Vitaly Lipatov authored 
      When a .list is moved between groups whose `gateway` files differ
in metric semantics (e.g., failover→multipath), the previous code
only deleted state and kept the table.  This caused stale routes
with the old `metric N` to coexist with newly loaded multipath
routes, because `ip route replace` keyed on dst+metric and treated
them as distinct entries.

Two related changes:
- cleanup_state's "moved" branch now flushes the table before the
  new group loads it, so the table starts clean.
- cleanup_state is invoked before process_routes so the flushes
  happen prior to the new group's load (otherwise a flush after
  load would wipe out the just-installed routes).
