clawbot c513816a55 Refuse [::], 0.0.0.0, IPv6 multicast and documentation space (closes #341)
check / check (push) Successful in 3m20s
On the build host a connection to [::] reaches a listener on ::1, and one to 0.0.0.0 reaches 127.0.0.1, so a delivery target at either reached this host's loopback past the guard. 0.0.0.0/32 and ::/128 are now in alwaysBlockedNetworks, which no allowlist opens; an allowlist reaches loopback only through an entry covering a loopback address. IPv6 multicast (ff00::/8) and documentation space (2001:db8::/32) are refused by default and reopen when listed.

Every default blocklist entry has a one-line comment, each list is pinned on its own, and tests refuse each address at target creation and at delivery. The README and the rules above each list match.

clawbot 38157d8936 Say how to allow a refused private target address (closes #398)
check / check (push) Successful in 3m16s
Refusing an http or slack target whose address is private or reserved, on add or edit, now adds one sentence: such addresses are refused by default, and the server's ALLOWED_EGRESS_CIDRS setting allows named networks, with a pointer to the README section. It suggests no value, so it never points at allowing everything.

Metadata refusals get no such sentence. To tell them apart, the default blocklist's public addresses now have their own list, blockedPublicNetworks, still checked after the allowlist; a test pins which addresses each list refuses and how listing opens them, unchanged from before.

clawbot f755c03110 Default-block Azure WireServer's public address (closes #245)
check / check (push) Successful in 4m34s
Add 168.63.129.16 (Azure WireServer) to blockedNetworks, the default
blocklist, not alwaysBlockedNetworks: it is public unicast, so an
operator who lists it in ALLOWED_EGRESS_CIDRS can reach it again. The
refusal message, the allowlist startup warning, the README and the
comments no longer call every blocked address private/reserved, and
no longer claim the allowlist cannot open any metadata endpoint.

Deviation: 147.75.207.243 (Equinix Metal) is not added; Equinix
documents only a hostname, and the service was sunset on 2026-06-30.
