Pin the share receipt's slug guard: a label equal to the home slug must fall back to "your friend" #1008

Owner: Dev2

What

plugins/social/src/social.js:2743-2746 (main d24c47c8) drops the click's row label and falls back to your friend when that label is the home key's slug:

const slug = homeKey ? String(homeKey).replace(/^@/, '').replace(/\.home$/i, '') : ''
const rowLabel = cleanText(friendName)
const who = (botName ? (ownerName ? `${botName} (${ownerName})` : botName) : ownerName)
  || (rowLabel && rowLabel.toLowerCase() !== slug.toLowerCase() ? rowLabel : '')
  || 'your friend'

The branch does its job — nothing tests it. Reviewer's evidence on #1002 (6385858050): replace that condition with true and both #994 tests stay green (# pass 2 / # fail 0). A refactor can therefore put the slug back into the receipt and CI stays quiet — the one thing #994 was about.

Expected

A caller that passes friendName equal to the home slug (any case, with or without @/.home) gets

Shared Chief with your friend. They can decline; you can Revoke in People with access.

and the message never matches /selftestb2/i.

Scope

• plugins/social/test/social.test.js — extend the existing Share receipt still says "Shared Chief with selftestb2" — the Bot that got the grant is not named #994 case (test('#994: the share receipt names the Bot the click granted and never the home slug', around :11264-11298). After the bare assertion add a third call: call('flybot/social/share-with-friend', { botId: chief.id, home: writer.home, peerBotId: 'pb-writer', friendName: 'selftestb2' }), then assert the exact your friend line and assert.doesNotMatch(msg, /selftestb2/i). Three assertions, no new helper.
• plugins/social/src/social.js:2746 is the code under guard; leave it alone unless the new case shows the branch is wrong.
• No core/, no patches/ds-bot/ mirror (test only). No changelog.d/ fragment: the user sees no change (changelog.d/README.md).

Acceptance

1. New assertion green on the tip, and the whole plugins/social file stays green.
2. Knife: change the guard at social.js:2746 to true ((rowLabel ? rowLabel : '')) → only the new assertion goes red, both existing Share receipt still says "Shared Chief with selftestb2" — the Bot that got the grant is not named #994 assertions stay green. Restore.
3. Second knife, optional: 'Writer (SelfTest B2)' and 'selftestb2' must land on different lines — a real label wins, the slug never prints.

Not this issue

• The other non-blocking on Name the Bot that got the share in the receipt (#994) #1002 (a row that draws only a handle does not send it as friendName, so the receipt says your friend while the panel shows a handle) is a client-side wording question, tracked on that PR, not here.
• Share receipt still says "Shared Chief with selftestb2" — the Bot that got the grant is not named #994 itself is closed (dcbf6ade); this is the missing test, not the fix.
