feat: slice 4 - the open management issues live in the repo

Gate 4, slice 4: 26 open management issues imported from live git.lab
(read-only, descriptions included as authorized; GitLab iid = file id,
labels/milestone/priority/due/host/area mapped into frontmatter, the
import aborts instead of inventing a missing milestone or priority).
Two new issues close the F-004 gap where work was really still open
(0033 OVERMIND-01, 0034 CFGMON-11 incl. the plaintext npm-token
rotation); CFGMON-12/13 already route to verified git.lab issues,
MATRIX-05 is done and needs none (agreed with sorb). The three wiki
task blocks now reference their issues, roadmap.md hands all counts to
the generated STATUS.md and states M1-M5 per ADR-0010 (closing F-001
in the canonical prose), pruefe_prosa joins the CI validate job, and
the import protocol under docs/sources/migration/ records every
intervention into imported text.

Verified: validate 0/0 over 29 issue files, gen_status --check current
(distribution line M1 9 - M2 17 - M4 2 plus per-issue milestone and
priority), pruefe_prosa 0 errors with clones and 0 errors/15 unchecked
citations in offline CI mode, drift check green.
