Host/core messages and zh strings still say 'Bot settings → Invite to this Bot' after #504 #506

Owner decision: approved (Danyang Chen, 2026-10-20 14:30 Asia/Shanghai).

Problem

#504 (still open at filing) renames the Sharing button to Copy invite link for and updates README / docs / plugins/social/client.js, but host/core messages and zh strings still tell the user to use Bot settings → Invite to this Bot. Once #504 lands these point at a button that no longer exists. (Do after / on top of #504.)

Affected spots (git grep "Invite to this Bot" on main b1ab6e4, excluding files #504 already changes)

User-visible (must change):

• core/src/host/room-membership.js:485 — ungranted-local refusal: Share … with ${friends} (Bot settings → Invite to this Bot), or leave … out.
• patches/ds-bot/files/src/host/room-membership.js:485 — same (patch copy; regenerate the corresponding patch)
• core/src/client/i18n.js:87 — 'Could not create the invite. Use Bot settings → Invite to this Bot.' + zh 请在 Bot 设置里使用 Invite to this Bot。
• core/src/client/new-chat.js:77 — setFixNote(t('Could not create the invite. Use Bot settings → Invite to this Bot.'))
• core/client.js:124, 10427 — bundled copy of the above (rebuild)
• patches/ds-bot/0001-core-fixes.patch:309 — i18n key + zh string
• patches/ds-bot/0003-flybot-api-client.patch:1214 — new-chat.js setFixNote
• patches/ds-bot/0008-client-bundle.patch:67, 8221 — bundle copies
• Tests: core/test/remote-room.test.js:919, patches/ds-bot/files/test/remote-room.test.js:919 (/Invite to this Bot/)

Comments / docs (update for consistency):

• core/src/host/hooks.js:936, core/src/host/reach.js:10, core/types/flybot.d.ts:34 (+ patches/ds-bot/files/... copies)
• plugins/social/src/social.js:10, plugins/social/README.md:21, plugins/tree/README.md:17, plugins/tree/src/adapter.js:13, plugins/tree/src/middleware.js:10
• docs/subsystems/social.md:13, 48, docs/subsystems/team.md:75

Fix

Point messages at Sharing → Copy invite link for (e.g. Share it with ${friends} (Bot settings → Sharing → Copy invite link for ${name})), with matching zh strings (keep the i18n key and string in sync across core, bundle and patches). Update the tests' regex. After the change, git grep "Invite to this Bot" should return nothing outside changelog history.
