jackandClaude Fable 5 4093ee6733 Rebuild Arti from audited source with enforced provenance
Vendored arti.xcframework rebuilt from source (Rust 1.96.0, normalized
archive metadata for reproducible hashes). New ARTI-BINARY-PROVENANCE.md
records toolchain, rebuild steps, and a SHA256 manifest for every file
in the xcframework. A new CI workflow turns that policy into a gate:
PRs must keep the binary matching the manifest, and binary changes must
ship with source/lockfile/build-script evidence.

Also raises TorManager.awaitReady's default timeout from 25s to 75s to
match the bootstrap monitor deadline - a shorter wait reported "not
ready" while Arti was still legitimately bootstrapping, silently
stranding queued relay work.

Privacy policy, Tor integration doc, and privacy assessment updated to
match the current implementation.

# The Arti xcframework is a vendored binary; these checks turn the policy in
# docs/ARTI-BINARY-PROVENANCE.md into an enforced gate:
# 1. The checked-in binary must match the hash manifest in the provenance doc.
# 2. A PR that changes the binary must also change at least one provenance
# input (Rust source, lockfile, build script, or the doc itself).
