fix: Resolve 3 P1 bugs and add --body-file flag to bd create

- bd-06px: Add --no-git-history flag to import command for sync subprocess compatibility
- bd-0zp7: Add missing hook calls (EventMessage in mail reply, EventClose in mail ack)
- bd-hy9p: Implement --body-file and --description-file flags for reading descriptions from files

Also closed stale issues that were already fixed:
- bd-0d5p: macOS test timeout (already fixed with SysProcAttr)
- bd-7yg: Merge driver placeholders (already using correct %A %O %A %B)
- bd-4ri: Test deadlock (test passes in 0.04s now)
- bd-b3og: TestImportBugIntegration (test no longer exists)
