The problem

A mod that keeps per-save state has no way to be told when a save is written or loaded. KSA raises no event for either, so the only signal is polling universe.xml's timestamp, which misses a save and load that happen inside one poll.

The change

Two lifecycle attributes, following the existing ones:

[StarMapAfterSave]
public void OnSaved(DirectoryInfo saveDirectory);

[StarMapAfterLoad]
public void OnLoaded(DirectoryInfo saveDirectory);

Both pass the save's directory, because a save is a directory and what a mod usually wants is a file beside universe.xml.

• StarMapAfterSave is a postfix on UncompressedSave.Make(string), which every save, overwrite and save-as goes through. It is not called when the write fails (Make returns null).
• StarMapAfterLoad fires after UncompressedSave.Load(), but only when that load reached Program.OnGameLoaded(). Load returns early when a save cannot be read, so a postfix on it alone would report loads that never happened; OnGameLoaded is called only once Universe.DeserializeSave has rebuilt the world.

How it is wired

• Rebased onto main and moved onto the new PatchManager. SaveLoadPatches registers the patches once, owned by StarMap itself (mod null), like the menu and restart patches, and dispatches to every mod's attributed methods through ModRegistry. Registering per mod would take each mod's one slot on these methods, so a mod could not then patch Load itself.
• Each mod's callback is invoked in its own try/catch, because these run inside KSA's save and load: one mod throwing must not stop the others or break the save.
• If any of the three methods is missing in a future KSA build, StarMap logs a line and runs without that hook rather than failing at startup.
• docs/modding/lifecycle.md lists both attributes.

Verification

• Builds with no warnings against KSA 2026.10.19.5638.
• The three targets are the methods KSArmory has patched in play since 2026-10 (its SaveHook and WorldReloadHook), checked against the decompiled 5638 source.
• Not yet run in game as a StarMap build.

Building note: the Debug configuration on main does not reference Planet.Core.dll or Planet.Render.Core.dll, which ConfirmRestart needs, so Debug does not compile against a plain Import/ folder. I added those two references from outside the repository to build; this PR does not change the csproj.
