fix(#3131): re-wire 4 orphaned workflows as flags on parent commands

- discuss-phase --assumptions  → list-phase-assumptions.md
- pause-work --report          → session-report.md
- manager --analyze-deps       → analyze-dependencies.md
- import --from-gsd2           → gsd-tools.cjs from-gsd2 CLI

TDD: 8 new assertions in enh-2790-skill-consolidation.test.cjs
(argument-hint presence + body dispatch reference per flag).
Confirmed RED before wiring, GREEN after. Full suite 6971/6971.

help.md updated with all four new flag forms to satisfy
bug-2954-help-md-slash-command-stubs parity test.

Closes #3131
