Completes the parallel tutorial set across all three implementations.
Python now has the same friendly step-by-step walkthrough that the
Rust and Node sides have had since the original tutorial commits.
Python tutorial content mirrors the others 1:1, adapted for the
Python invocation style (.venv/bin/python kez_cli.py …), plus:
• Programmatic section uses Python imports (NostrSecret.from_nsec,
sign_claim, default_registry, etc.) instead of the TS imports
from the Node tutorial.
• Same "Recovery phrases" mini-chapter as rust/nodejs — both 12-word
AND 24-word are explained, with the entropy table, picking guide,
hardware-wallet-incompatibility callout, concrete backup advice
("pencil + paper, numbered words, fireproof, don't split,
don't permute"), and "Working with phrases later" examples
(`identity mnemonic`, `identity from-mnemonic`).
• Notes that `sigchain publish` isn't in the Python CLI yet (only
add/revoke/show/export) — match the actual current surface; the
JSONL the Python CLI produces is byte-compatible with Rust/Node,
so users can build the chain in Python and publish via either
of the other CLIs in the meantime.
• Troubleshooting includes ModuleNotFoundError: kez (a Python-
specific footgun when running outside the venv).
• Links to ../rust/TUTORIAL.md and ../nodejs/TUTORIAL.md as parallel
references throughout.
python/README.md now opens with the same "New to KEZ? Read TUTORIAL.md"
callout as the rust and nodejs READMEs do.
Root README's quick-start blocks for each implementation now reference
BOTH the impl README (reference) AND the impl TUTORIAL (step-by-step,
on-ramp) instead of just the README.

Add a Python port of the KEZ CLI under python/, mirroring the Rust and
Node implementations command-for-command and byte-for-byte:
- Pure-Python JCS (RFC 8785), BIP-340 Schnorr, and Bech32; cryptography
for Ed25519 and zstandard for the compact zstd framing.
- Full CLI: identity new, claim create/dns, verify file, and
sigchain add/revoke/show/export.
Wire Python into crosstest.sh with 35 new scenarios covering Python
against both Rust and Node, in every direction, across all wire formats,
both key types, DNS proofs, and sigchains (incl. JSONL byte parity).
All 55 scenarios pass.
Update root README and .gitignore for the new implementation.
