ef7ae06ffc point 2 + 3: LOCA entry reach + scram fat-entry + steam-dump heatup
Morning-review items 2 and 3.

Point 2 (scram X_entry expansion):
  - reach_loca_operation.jl: LQR reach under Q_sg widened to
    [0, 1.5*P_0] (steam-line break envelope) for 3 s horizon.
    Longer horizons cause numerical blowup in the box-hull
    reach propagator due to slow precursor modes amplifying
    under large disturbance — documented in the script.
  - reach_scram_pj_fat.jl: computes bounding-box union of
    hot-standby + heatup-tight + operation + LOCA reach
    envelopes, clamps obvious numerical outliers on precursors
    and temperatures, builds a fat X_entry(scram), runs scram
    PJ reach. Result pending (TMJets compiling).

Point 3 (heatup steam-dump Q_sg):
  - configs/heatup/with_steam_dump.toml: Q_sg ∈ [0, 0.05·P_0]
    as bounded parameter.
  - reach_heatup_pj_sd.jl: 12-state RHS with x[10]=Q_sg (dx=0,
    augmented bounded param) and x[11]=t. Running in
    background.

Tight-entry heatup via the new TOML-config reach_heatup_pj.jl
reproduces the previous all-6-halfspaces-discharged result
(300s horizon, T_c envelope [281.05, 291.0]). Refactor
preserves semantics.
