v2.5.0 - September CS2 Protocol Refresh

Added

• Latest pet protocol module and ackPetEvent(petItemId) fire-and-forget helper with uint64 validation
• Inspection fields customnames, pet_food_expiration_date, and blobdata, with TypeScript declarations
• New upstream clan tags, encrypted network messages, remote server commands, serialization settings, and network performance metrics

Changed

• Synced all 44 upstream protobuf files through GameTracking-CS2 commit 3fc98e763328f7d1627405b389d1b6b69c5b0e38 (September 25, 2026): eight changed files and one new file
• Regenerated all 44 schema modules and their loader
• Preserved inspectItem()'s customname field as the last entry in customnames, or null, matching the previous singular protobuf decoder
• Pinned each protobuf download run to one upstream commit; PROTO_REF optionally selects a snapshot

Compatibility

• Direct consumers of generated protobuf modules must use customnames instead of customname when encoding inspection data. The public inspectItem() API retains its compatibility alias.
• Upstream renamed legacy chat/team-money enum entries with the _CSGOLegacy suffix and removed the obsolete weapon-sound stealth field.
• Live Steam/GC operations have not been tested; the pet protocol defines no acknowledgement response.

Validation: 185 offline tests and ESLint pass; all 45 generated files reproduce exactly. The packed npm artifact passes a consumer smoke test on Node.js 24.21.0.
