Rename configd + IPConfiguration plans to nextbsd-*; reconcile them with the WLAN plan

Both docs are the Mach-IPC track (MIG over mach_msg, com.apple.SystemConfiguration),
not the superseded AF_UNIX/DO sockets track — they were never FreeBSD-only work, so
the freebsd-* prefix was wrong:

  freebsd-configd-plan.html         -> nextbsd-configd-plan.html
  freebsd-ipconfiguration-plan.html -> nextbsd-ipconfiguration-plan.html

Both are now listed in nextbsd-research.html. All ~38 inbound links repointed, and
link text updated to match.

Content drift fixed. Both plans predate the WLAN plan and contradicted it:

  configd
  - claimed configd would read wpa_supplicant's control socket and populate
    State:/Network/Interface/<iface>/WiFi. Wrong key AND wrong owner: the key is
    .../AirPort and *wland* publishes it, like any other SCDynamicStore client.
    No configd change is required for WLAN at all.
  - argued security/wpa_supplicant from ports should supersede base. Rejected: it's
    the same 2.11, installs to /usr/local/sbin, and shadows base for no benefit.
    We keep wpa_supplicant stock from base — not vendored, not taught Mach.
  - "WiFi declarative config" in Phase 8+ reassigned to wland (it owns known networks
    in SCPreferences and is sole author of wpa_supplicant's network blocks).
  - the WiFi-credentials open question moved to WLAN plan Q2, where it belongs.

  IPConfiguration
  - claimed WLAN association state would arrive "via a wpa_supplicant hook". No such
    hook exists here — that was dhcpcd's, and NextBSD replaced dhcpcd with ipconfigd.
    State arrives as wland's AirPort key; ipconfigd grows the ~70-LOC sc_link_watch.c
    gate requiring Link{Active} AND AirPort{Authenticated}, key-absent meaning ready
    so wired NICs are untouched.
  - now records that "one interface, Ethernet only" is not merely unbuilt but two real
    bugs — dead re-arm after lease expiry (#37) and a global single-flight capping the
    daemon at one bound interface for its lifetime (#38) — both hard blockers.

Redirect stubs at the four old paths (incl. the two wifi docs from c6d390a) so existing
bookmarks and shared links keep working.

Also fixes a dangling href to freebsd-hwregd-plan.html, a doc that never existed; the
real target is freebsd-hardware-registry-iokit-plan.html. Every internal link on the
site now resolves.

Mach IPC is <strong>retained</strong> for the daemon's <code>DiskArbitration.framework</code> client API (MIG IDL <code>da.defs</code>, Mach service <code>com.apple.DiskArbitration</code>, <code>DISPATCH_SOURCE_TYPE_MACH_RECV</code> event loop). <code>libgeom</code> is used only for partition / UUID / label / FS-type <strong>enrichment</strong>, in-process, not as the event source.

     <li><strong>Mission:</strong> stop shipping <code>FreeBSD/amd64 (Amnesiac)</code>. Synthesize a hardware-derived default name (<code>ThinkPad-T420-8AB123</code>, <code>Mac-mini-F12345</code>, &hellip;), publish via SCDynamicStore so mDNSResponder has a real <code>.local</code> name to announce, and respect user overrides via SCPreferences once that surface exists.</li>

Standalone daemon is the consistent shape; if a plugin loader lands later, <code>hostnamed</code>'s body lifts into a plugin in &lt;200 LOC of glue.</li>
     <li><strong>Source: hybrid &mdash; vendor where Apple has open source, clean-room where it doesn't.</strong> Apple's modern hostname pipeline lives in <strong><code>Plugins/IPMonitor/set-hostname.c</code></strong> (rolled into IPMonitor in recent configd; there is no standalone <code>SetHostname</code> plugin anymore). That file is APSL 2.0, ~500 LOC, and implements <strong>precedence-based decision + DHCP option 12 + reverse-DNS PTR fallback + the notify_post broadcast</strong>. What it does <em>not</em> do: synthesize a default name from hardware identity &mdash; that lives in Setup Assistant (closed source) on real Macs. So our daemon ports the open-source piece verbatim and clean-rooms the synthesis fallback that fills Setup Assistant's role.</li>
     <li><strong>Wire shape:</strong> launchd job at boot &rarr; reads <code>kenv</code> + SMBIOS for synthesis fallback &rarr; (iter 1) writes synthesized name to SCDynamicStore <code>Setup:/System</code> + <code>Setup:/Network/HostNames</code> via <code>libSystemConfiguration</code> &rarr; calls <code>sethostname(2)</code> &rarr; <code>notify_post("com.apple.system.hostname")</code> &rarr; exits. Later iters add SCPreferences awareness, the vendored <code>set-hostname.c</code> precedence/DHCP integration, and Bonjour-conflict feedback.</li>
     <li><strong>Licensing:</strong> mixed. Vendored Apple files (iter 3+ <code>set-hostname.c</code>, possibly bits of <code>SCDHostName.c</code>'s validation helpers) stay APSL 2.0 with their original headers, exactly like configd / IPConfiguration. New clean-room synthesis + glue stays BSD-2-Clause. Same per-file pattern the rest of <code>freebsd-launchd-mach</code> uses.</li>
