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.
