Client-mod API consolidation release — high-level Python interface, cleaner extension exports, and client/runtime hardening and readability improvements.

Changes

ClientMod Session-First API

• Consolidated extension entrypoints around client_mod from bridge.extensions.client_mod.
• Standardized per-player calls through ClientModSession (cm = client_mod.session(player)) and methods like cm.command(...), cm.register_script(...), cm.raycast(...), cm.stream_audio_file(...), and cm.stream_audio_generator(...).
• Exposed singleton decorators/registries for event and payload wiring: client_mod.on_client_data, client_mod.on_permission_change, client_mod.register_request_data(...), client_mod.unregister_request_data(...).
• Normalized exports in bridge.extensions to favor object-based API usage (ClientMod, ClientModSession, client_mod) over flat helper-only usage.

BridgeInstance and Event Routing Correctness

• Added script-only event bookkeeping via BridgeInstance.scriptOnlySubscriptions so BridgeInstance.hasSubscription(...), BridgeInstance.getSubscriptionNames(), and dispatch matching include script-local handlers.
• Added BridgeInstance.resolveInvokeResult(...) to correctly resolve nested CompletableFuture returns with timeout/error propagation into Python responses.
• Corrected broadcast path in BridgeInstance to return server.broadcastMessage(...) behavior instead of log-only side effects.
• Hardened material handling in BridgeInstance (sendBlockChange) with explicit Material.matchMaterial(...) null checks before Bukkit.createBlockData(...).

Serializer/Facade Guard Rails

• Added BridgeSerializer inventory validation in deserialize(...) (size must be 9..54 and a multiple of 9).
• Removed implicit world mutation from BridgeSerializer Block deserialization (no hidden block.setType(...) side effects).
• Tightened boolean coercion in BridgeSerializer.coerceArg(...) to explicitly parse "true" / "false" string inputs.
• Added operation volume/bounds enforcement in RegionFacade.pasteOperations(...) and stronger invalid block-data failure behavior in RegionFacade.parseBlockData(...).
• Enforced protocol-version validation in ClientModFrameCodec.decodeFrame(...).

Python Runtime Concurrency and Lifecycle Safety

• Added BridgeConnection locking around _pending_sync and batching (_pending_sync_lock, _batch_lock) to avoid races between reader/caller threads.
• Made BridgeConnection.flush() atomically snapshot/clear _batch_messages and _batch_futures before sending call_batch.
• Added atomic abort reporting: server.atomic() now yields an int-like counter (with server.atomic() as num_failed: / async with ...) and server.flush() returns the aborted-call count for the flushed batch.
• Hardened disconnect/shutdown behavior in BridgeConnection so pending sync waits are finalized safely and loop stop is scheduled via _loop.call_soon(...).
• Added proxy handle refcount synchronization in wrappers.py (_handle_refcounts_lock) and deterministic LRU-like UUID cache helpers (_cache_get_player_uuid, _cache_set_player_uuid).

Extension Correctness and Recovery Paths

• Prevented duplicate updater loops by task dedupe/cancel logic in ability.py, combat.py, quest.py, leaderboard.py, scheduler.py, and state_machine.py.
• Added malformed persistence recovery for JSON-backed extensions (bank.py, levels.py, player_data.py, guild.py).
• Fixed transactional currency flow in trade.py by checking bank.withdraw(...) return values and refunding on partial failure.
• Tightened parsing/validation across build and content tooling (dungeon.py, schematic.py, mesh_display.py, image_display.py, loot_table.py, tab_list.py).
• Improved client audio stream cleanup/failure surfacing in client_mod.py (ffmpeg stdout checks, producer error propagation, guaranteed stop in finally).

Docs, CI, and Packaging Follow-Through

• Reworked docs keying in docs/build.py to avoid basename collisions in output names, source maps, and search URLs.
• Pinned .github/workflows/deploy-pages.yml tool dependencies for reproducible docs deployments.
• Added missing extension files to src/main/resources/python/bridge/MANIFEST (loot_table.py, placeholder.py, scheduler.py, schematic.py, state_machine.py, tab_list.py).
• Updated stubs to reflect API/type reality in bridge/__init__.pyi and bridge/extensions/__init__.pyi.
• Moved search index and git metadata from page files into seperate files. For faster loads and better SEO.
• Added --production flag, which converts all links to absolute links (/PyJavaBridge/world.html instead of /world.html) for better SEO.
