fix: avoid duplicate group prefix in scoped --llms output

[Ryan-Ouyang]

Problem

When --llms / --llms-full (markdown) is scoped to a command group, the group prefix is applied twice — producing command signatures like:

$ cli auth --llms
| `cli auth auth login`  | ... |
| `cli auth auth logout` | ... |

instead of the correct cli auth login. This affects every group, whether built as a sub-Cli or generated from an OpenAPI spec, and shows up in both --llms and --llms-full.

Root cause

In the scoped --llms markdown branches, the prefix is double-counted: it's folded into scopedName and passed into collectSkillCommands, which bakes it into each cmd.name (path = [...prefix, name]). Skill.index/Skill.generate then render ${scopedName} ${cmd.name}.

The unscoped call sites (and the JSON/YAML manifest path, which doesn't prepend scopedName) already pass [], which is why root cli --llms and --format json were correct.

Fix

Pass [] to collectSkillCommands in the two scoped markdown branches so command names stay relative to the already-prefixed scopedName.

Tests

• Updated Cli.test.ts scopes to subtree — it previously asserted the buggy test auth auth login output (which is why this slipped through). It now asserts test auth login plus negative assertions against the duplicated form.
• Regenerated the two e2e.test.ts inline snapshots that had captured the doubled output.
• Full suite green, lint + types clean.
