Khalim Conn-Kowlessar a9faaddc1d docs: handover for Table 3a no-keep-hot continuation + SAP 10 spec PDFs
Adds the next-agent handover and the BRE technical papers referenced
by the cohort-2 negative-band investigation:

  - `HANDOVER_TABLE_3A_NO_KEEP_HOT.md` — picks up from Slice S0380.20.
    Covers cohort distribution at HEAD `4879e8c3`, the verified
    Table 3a Row 1 spec formula `(61)m = 600 × fu × nm / 365`, the
    dispatch recipe for `pcdb_combi_loss_override`, watch-outs (cert
    0360 / cohort-1 cert 000490 behaviour after the slice lands), the
    diagnostic probe script, test baselines, and the open-thread
    priority list (Ext1 roof, HP-COP, big-gap 2102, API path, parity).

  - `specs/STP09-B04_Combi_boiler_tests.pdf` — 2009 BRE methodology
    paper (Alan Shiret, BRE) defining the combi-loss test programme
    that produced the SAP Table 3a 600/900 kWh/yr keep-hot assumptions.
    Source: https://bregroup.com/documents/d/bre-group/stp09-b04_combi
    _boiler_tests.

  - `specs/sap10 technical papers/S10TP-{02..13}.pdf` — full SAP 10
    supporting technical paper set (Issue 1.2 / 1.3 / 1.4 across the
    eight papers). S10TP-12 §9.4 confirms: "No changes to the SEDBUK
    calculation method for water heating efficiency were considered
    necessary" — so the STP09-B04 (SAP 2009) Table 3a methodology
    carries through to SAP 10 unchanged.

These docs replace web-fetched references with locally-tracked copies
so the slice S0380.21 implementor can grep / pdftotext them directly.
