`crates/cli` docs are stale: parity table marks shipped commands as not implemented, `enr` help names a nonexistent key file

[emlautarom1-agent]

Summary

Two documentation defects in crates/cli:

1. README.md last changed on 21 April. Its Charon-parity table marks eleven commands as "Not implemented" that ship today, and its "Commands (current)" section documents only three of the eight top-level commands the binary exposes.
2. pluto enr --help tells the operator to look for a file that does not exist.

Parity table rows that are wrong

Marked ❌ at README.md#L61-L85, all present in cli.rs:

Command	Landed
run	#503, 2026-07-07
unsafe, unsafe run	#503, 2026-07-07
relay	#224, 2026-02-27
dkg	#316, 2026-04-23
alpha, alpha test + all/peers/beacon/validator/mev/infra	#149, 2026-02-16

Genuinely still unimplemented, and correct as-is: combine, alpha add-validators, exit and its five subcommands.

Wrong key filename in enr help

cli.rs#L39 reads:

long_about = "Prints an Ethereum Node Record (ENR) from this client's pluto-enr-private-key. This serves as a public key that identifies this client to its peers."

No such file is ever produced or read. KEY_FILE_NAME in p2p::k1 is charon-enr-private-key; dkg::disk requires it under that name; run's --p2p-private-key defaults to .charon/charon-enr-private-key. This is also the one place the string appears — pluto-enr-private-key has no other occurrence in the tree.

Charon's cmd/enr.go Long is otherwise identical and names charon-enr-private-key, so the fix restores parity as well as accuracy.

Work

• cli.rs: change pluto-enr-private-key to charon-enr-private-key in the Enr variant's long_about.
• README.md: flip the eleven stale rows to ✅ and drop their "Not implemented" notes.
• README.md: extend "Commands (current)" to cover run, relay, dkg, alpha test and create cluster with their flags, matching the depth of the existing enr and create entries.

Acceptance

• Every ✅/❌ in the parity table matches the subcommands pluto --help actually exposes.
• A reader can find every implemented top-level command in the prose section.
• No help text or doc names a key file the binary does not use.
