mak:teardown — Remove the mak Block from the Global CLAUDE.md

Reverses mak:setup: deletes the marker-delimited block from ~/.claude/CLAUDE.md. Content outside the markers is never touched.

Procedure

1. Read ~/.claude/CLAUDE.md.
   • If it does not exist, or contains no <!-- mak:begin marker: report "nothing to remove" and stop.
2. Remove the block — delete everything from the <!-- mak:begin marker line through the <!-- mak:end --> marker line, inclusive. Collapse any resulting runs of 3+ blank lines to one.
   • If a begin marker exists without an end marker, or more than one begin/end marker exists (corrupted/duplicated state): do not guess the block boundary. Show the user the marker locations and ask how far to remove.
3. If the file is now empty or whitespace-only — tell the user; offer to delete the file or leave the empty file (their choice). Do not delete it unprompted.
4. Report — state that the block was removed. If ~/.claude/CLAUDE.md.mak-backup exists, mention it: it holds the pre-setup snapshot and can be deleted by the user once they're satisfied, or used to compare (diff) if anything looks off. Do not delete the backup automatically.

Cautions

• Only the marker-delimited block is removed. Never remove legacy (pre-plugin) manually-pasted sections here — that was only offered during mak:setup with confirmation.
• Do not run git commands; ~/.claude may not be a repository.
