docs(link): record world.ruleset and mark Protocol 3.0 progress

Protocol 3.0 order 2 (v3.md §5) is built across all four repos; this is its
documentation half, plus the running progress record the plan was missing.

v3.md
  - A progress table at the top and a State column on §9's sequencing table, so
    "what has landed" is answerable without reading four git logs. Part A (order
    1) and world.ruleset (order 2) are marked done; the spawn atlas is next.
  - §5 gains the implementation notes worth keeping, chiefly: where a system's
    on/off state is DERIVED rather than configured, read the system's own static
    instead of inventing a .cfg key (Shadowguard has no Enabled key — it's the
    TOL expansion gate; Factions is `!ViceVsVirtueSystem.Enabled` by
    construction in stock ServUO). Also that the plugin CAN be compile-verified
    despite the "no standalone build" caveat, and how.

INTEGRATION.md
  - The world.ruleset catalog entry and GET /ruleset, with the two things
    consumers get wrong: caps are in TENTHS (1000 = 100.0), and `connect` exists
    only if the operator set Bridge.PublicConnectAddress — the shard's real
    listen address is never published.
  - §2 now says plainly that v3 has NOT been bumped yet and what that means:
    sidecars on `edge` report 2 while already carrying some v3 kinds, so do not
    infer feature availability from the version during this window.

PROTOCOL_2.md §10.4
  - The deferred "which PvP system does this shard run?" is answered (VvV on,
    Factions off — and mutually exclusive by construction), and world.systems is
    marked superseded by world.ruleset, which carries the systems block it asked
    for. No orphan kind is left behind.

BACKEND_DESIGN.md — the shard_ruleset table (why it is stored whole rather than
normalized, and why no row means null rather than {}) and the public route.

PROJECT_TREE.md is deliberately untouched: sync-project-tree regenerates it on
push to main, so it updates itself at the v3 cutover.

+
+- ***`shadowguard` is derived, not configured.*** `Shadowguard.cfg` carries only `ReadyDuration` and
+  `RandomizeInstances` — there is no `Enabled` key — so the systems block reports `Core.TOL`
+  (the expansion gate) instead. Same shape for `factions`: `Factions.cfg` has no `Enabled` either, and
+  `Services/Factions/Core/Faction.cs` sets `Settings.Enabled = !ViceVsVirtueSystem.Enabled`, so the
+  frame reads that static rather than inventing a key. **Where a system's on/off state is derived, read
+  the system's own static; only read `Config.Get` where the .cfg key IS the truth.**
+- **`caps.skill` / `caps.totalSkill` are in tenths** (1000 = 100.0), the way ServUO stores them.
+  Documented in `INTEGRATION.md` and converted in the client, because the raw number is actively
+  misleading rather than merely unhelpful.
+- **`Config.Get` re-parses when the cached type differs.** `InternalGet<T>` caches the parsed value on
+  the entry and re-parses if `entry.Object is T` fails, so reading `PlayerCaps.SkillCap` as an `int`
+  where ServUO reads it as a `double` is correct (both parse) — it just re-parses. Harmless, but worth
+  knowing before assuming a shared cache.
+- **The plugin CAN be compile-verified**, contrary to "no standalone build": point Roslyn
+  (`dotnet sdk/*/Roslyn/bincore/csc.dll`, `/langversion:7.3`, net48 reference assemblies) at the whole
+  ServUO `Scripts` tree with `overlay/Scripts/Custom/Bridge/*.cs` substituted for the deployed copy,
+  excluding `Scripts/obj` and `Scripts/bin`. 6,205 files, ~40 s, and it catches every signature error
+  a boot would. Worth doing before every plugin PR.
