Charon's Echo

No soul left stranded.

• Death portals can no longer rise somewhere you can't reach. The portal spot is found by walking outward from where you fell, the way the ghost itself moves - flying, drifting through water and lava, stopped by walls. A cave death puts the door in the cave; an ocean-floor death puts it on the sea bed beside you.
• When no door can rise, Charon comes himself. Die in a sealed pocket or the void and the moment the wake ends you are ferried straight to your grave in the Echo. No more stranded ghosts waiting for an admin.
• New config: instant-ferry (default off). For packs that want death to move fast: the moment the wake ends, the dead are ferried straight to their grave - no portal, no ghost walk. The wake and obol donations at the body still happen.
• /charon revive <player> now works from the server console and RCON - owners can rescue a soul without logging in. A revived ghost is set on solid ground first.

Also: dead-code cleanup and the codebase reorganized into per-system packages.
