feat(chat): the Maple bot in Hazel - #2016

🟢 Confidence 8/10 · likely safe to merge. Held at 8 because earlier reviews of this pull request found 5 defects.
_{no findings · tests covered · risk medium · 5 defects fixed in earlier rounds}

The last commit reworks stripMention so a Hazel mention is removed without collapsing the message's line breaks or the indentation of the line beneath it, with a test for both shapes. The change is safe to merge; the rest of the connector was reviewed at 35bba6e.

• stripMention joins split parts with a space only between words, never at a line edge
• Leading blank lines are dropped with trimEnd(), keeping the first content line's indentation

Before merge

• Secret · Add MAPLE_HAZEL_BOT_TOKEN and MAPLE_HAZEL_BOT_ID to the prd (and EU) secret stores · packages/chat-platform/src/connectors/hazel/api.ts:26
• Manual · Deploy MapleTechLabs/hazel#370 before this ships

Fixed since the last review

• ✅ F6 · stripMention's .trim() drops the indentation of an indented first line
