feat(compose): teaser + LP quarterly + exit memo composers

- compose_teaser: 6-slide anonymizable deal teaser (buyer/LP outreach)
- compose_lp_quarterly: 9-slide fund quarterly report (NAV/IRR/TVPI/DPI, holdings, movers, capital activity)
- compose_exit_memo: 8-slide exit recommendation (value creation bridge, returns-vs-underwrite, buyer landscape)

All three vertical-agnostic (pe/re/infrastructure/credit/npl/vc/m_and_a).
Finance-pro theme across the board. 38 new tests (13+11+14), 51/51 compose tests pass.

 """Deal-deck composers — turn structured deal data into DeckForge IR.
 
-Callers (CreditAI, Aither, any investment platform) POST a DealFacts payload
-to /v1/compose/ic-memo (or /teaser, /lp-quarterly, /exit-memo) and get a
-fully composed .pptx back. The IR composition lives here so the logic is
-shared across deck types and can evolve centrally.
+Callers (CreditAI, Aither, any investment platform) POST a facts payload to
+``/v1/compose/<type>`` or import these composers directly to get a fully
+validated Presentation IR, which they then POST to ``/v1/render`` for a
+.pptx binary.
+
+Available composers:
+
+- ``compose_ic_memo`` — 12-slide investment committee memo
+- ``compose_teaser`` — 6-slide anonymized deal teaser
+- ``compose_lp_quarterly`` — 9-slide LP quarterly fund report
+- ``compose_exit_memo`` — 8-slide exit recommendation deck
