feat: pip install rustchainnode — installable RustChain attestation node

[noxxxxybot-sketch]

pip install rustchainnode

Implements bounty #757.

Quick Start

pip install rustchainnode
rustchainnode init --wallet my-wallet-name
rustchainnode start

Milestones

Milestone	Status	Expected RTC
PyPI package — pip install rustchainnode installs and runs	✅	50 RTC
CLI: init, start, stop, status, config	✅	included
Auto-configuration — detects hardware, sets optimal thread count	✅	+10 RTC
Systemd/launchd service generation — rustchainnode install-service	✅	+15 RTC
Health dashboard — rustchainnode dashboard shows TUI with epoch, miners, balance	✅	+15 RTC
Cross-platform — Linux x86_64, aarch64, ppc64, macOS x86/ARM64	✅	+10 RTC

Total expected: 100 RTC

Programmatic API

from rustchainnode import RustChainNode

node = RustChainNode(wallet="my-wallet", port=8099)
node.start()
print(node.health())   # {"ok": true, "version": "2.2.1-rip200", ...}
print(node.epoch())    # {"epoch": 94, "slot": 13580, ...}
node.stop()

Cross-Platform Antiquity Support

Architecture	Antiquity Multiplier
PowerPC (G4/G5)	2.5x
PowerPC 64-bit	2.0x
x86 32-bit	1.5x
ARM64 / x86_64	1.0x

Zero Dependencies

Pure stdlib — no pip install flask needed to run the client CLI. Works on Python 3.9+.
