fix: Arbiter 3.0 production fixes from Gemini consultation

WHAT WAS FIXED:
Production deployment revealed silent sync failure. Root cause: Pterodactyl
API nest filtering was broken. Gemini consultation provided Solution C
(environment variable configuration) for robust, maintainable operation.

GEMINI'S RECOMMENDATIONS IMPLEMENTED:
1. Solution C: MINECRAFT_NEST_IDS environment variable (explicit control)
2. Comprehensive sync logging (visibility into each step)
3. 'lifetime' status support for The Trinity (owner access)
4. Early exit with warning when 0 servers discovered

ROOT CAUSE ANALYSIS:
Original code filtered servers by nest relationship name:
  server.attributes.relationships?.nest?.attributes?.name === 'Minecraft'

Problem: API doesn't include nest relationships in response, so filter
returned 0 servers, causing silent sync failure with no error logs.

Solution: Filter by nest ID directly using environment variable:
  allowedNests.includes(server.attributes.nest)

CHANGES:

.env.example:
- Added MINECRAFT_NEST_IDS=1,6,7 (Minecraft, NeoForge, Hytale nests)
- Explicit configuration instead of dynamic discovery
- User controls which nests to sync (adaptable to nest reorganization)

src/panel/discovery.js:
- Parse MINECRAFT_NEST_IDS from environment
- Filter servers by nest ID (not relationship name)
- Remove broken ?include=allocations,node,nest parameter
- Direct integer comparison (robust, predictable)

src/sync/immediate.js:
- Added comprehensive logging at each step:
  * Player count from database
  * Server discovery count
  * Success/failure counts per sync
- Added 'lifetime' status to query (for Trinity owner access)
- Early exit with warning if 0 servers discovered
- Per-server error logging with server name + identifier

PRODUCTION TESTING RESULTS:
✅ Discovered 12 target servers (nests 1, 6, 7)
✅ Retrieved 1 active player from database
✅ Synced successfully to all 12 servers (0 failures)
✅ Whitelist.json confirmed on Panel servers
✅ Logs show clear visibility into sync process

GEMINI ARCHITECTURAL GUIDANCE:
- Solution C preferred over dynamic discovery (predictable, no extra API calls)
- Manual whitelist enforcement (don't automate server.properties editing)
- Configure Pterodactyl Eggs with white-list=true for future servers
- Explicit configuration > keyword matching (prevents accidental overwrites)

DEPLOYMENT VERIFIED:
Command Center (63.143.34.217) running Arbiter 3.0 successfully syncing
whitelists to 12 Minecraft servers across nests 1 (Minecraft), 6 (NeoForge),
and 7 (Hytale).

SOFT LAUNCH BLOCKERS:
✅ Task #87 (Cancellation flow) - Webhook handlers ready
✅ Task #90 (Whitelist management) - DEPLOYED AND OPERATIONAL

FILES MODIFIED:
- .env.example (added MINECRAFT_NEST_IDS)
- src/panel/discovery.js (environment-based nest filtering)
- src/sync/immediate.js (comprehensive logging + lifetime status)
