This is a big one: an optional client-side display. The server is still drop-in and mod-less clients still work exactly as before — everything new degrades gracefully. This may also be the last update for this mod in general since it seems just about finalized in terms of functionality.

Added

• Optional client mod with an on-screen log. Install the mod on a client and shared events roll into a slow-fading log in a screen corner (top-right by default; corner, offset, scale, linger, and fade are all configurable in shareddamage-client.cfg). Clients without the mod are untouched and keep the chat / action-bar notifications.
• Event flash. Each log line briefly pulses in its category color when a new event lands — red for damage, green for healing and food gains, gold for hunger loss.
• Per-type notification channels. Damage, healing, hunger-gain, and hunger-loss each route independently to actionbar, chat, or off.
• Compact action-bar tokens (-3♥ +2♥ -1h) when more than one notification type shares the single action-bar slot.
• debugLogging toggle for per-hit diagnostics in the server console.

Changed

• Notifications reworked around coalesced, per-category lines with a configurable linger window.
• New defaults: hunger-loss notices are off, hunger-gain and healing default to chat, and damage stays on the action bar — keeping the action bar uncluttered out of the box.

Upgrading from 2.2.x

• This release adds new config keys and changes some defaults. Forge won't rewrite an existing config/shareddamage.cfg, so delete it (or merge the new keys by hand) to pick up the 3.2.0 defaults; a fresh install gets them automatically.
• For the client display, install the mod on the client too — the server alone is enough for sharing, but the corner log only appears for clients that have the mod.
