4grayandClaude Opus 5 a2b168127f fix(stalker): classify every portal-local IPv6 placeholder ...

Codex P2 on #1364, same class as the 127.0.0.0/8 one. `http://[::]/ch/1234_`
and the IPv4-mapped loopback forms slipped past the exact-name set and would
have been handed to the player as real addresses.

Checked how `URL` actually normalizes these rather than guessing at the
spelling a portal might use: brackets are kept, `[0:0:0:0:0:0:0:1]` collapses
to `[::1]`, and an IPv4-mapped address is rewritten to hex — `[::ffff:127.0.0.1]`
arrives as `[::ffff:7f00:1]`. The guard now strips the brackets, matches `::1`
and `::`, and decodes the mapped form by its high byte, so the whole of the
mapped 127.0.0.0/8 range is covered along with the mapped unspecified address.
The dotted tail is still accepted for any engine that leaves it alone.

Routable hosts are unaffected, pinned by tests for `[2001:db8::1]` and
`[::ffff:203.0.113.7]`. Mutation-checked: dropping `::` and the mapped-IPv4
decode fails five tests and nothing else.
