feat(cli): map v2 commands and v2 state to v3 guidance

[harlan-zw]

❓ Type of change

• 👌 Enhancement

📚 Description

Stable v3 moves npm latest off 2.3.0, so every v2 user lands on the native CLI. Their muscle memory currently gets this:

INVALID_ARGUMENT: unrecognized subcommand 'whoami'
INVALID_LOCKFILE: the Skill lockfile is not valid JSON
INVALID_SOURCE: use a skilld search selector or an explicit GitHub Repository selector

login, logout, whoami, info, and prepare now run their v3 replacement. The removed commands (author, watch, cache, and the rest) exit with REMOVED_COMMAND and link the migration guide. A v2 YAML lockfile says to back up .skills, and skilld add vue points to skilld search vue.

Not sure prepare → install is right. A v2 project still fails there, but on the lockfile message, which is at least actionable.
