Dane Sabo 2bbb1871cc refactor: scripts subdivision + TOML configs + results/ split + presentation outline

Architecture restructure from morning review:

1. code/scripts/ subdivided into sim/, reach/, barrier/, plot/.
   Easier nav; `barrier/` is the natural place for SOS scale-up scripts.
2. Heatup PJ reach variants consolidated behind TOML configs.
   reach_heatup_pj.jl now takes `--config path/to/config.toml`;
   configs/heatup/baseline.toml (wide entry, from predicates.json) and
   configs/heatup/tight.toml (narrow entry, reproduces all-6-halfspaces
   discharged result). Old reach_heatup_pj_tight.jl and
   reach_heatup_pj_tight_full.jl deleted (superseded).
3. Reach output .mat files moved from reachability/ to results/.
   reachability/ now = specs + docs; results/ = ephemeral outputs
   (gitignored *.mat). README added.
4. OVERNIGHT_NOTES.md archived to claude_memory/2026-04-20-21-overnight-
   session-summary.md (date range in the filename makes the history clearer).

All include() / Pkg.activate() paths in scripts updated for the new
depth. Smoke tests pass (reach_operation.jl generates its .mat in
the new results/ location; sim_sanity.jl matches MATLAB).

Presentation outline for the 20-min prelim talk landed in
presentations/prelim-presentation/outline.md. 14-slide assertion-
evidence format targeting OT-informed cybersecurity audience. Each
slide: one declarative assertion + one figure. Outline includes
which figures already exist and which need to be created, timing
checkpoints, cybersecurity angle to emphasize, and Q&A prep.

New config configs/heatup/with_steam_dump.toml + its companion
scripts/reach/reach_heatup_pj_sd.jl (12-state RHS with Q_sg as an
augmented bounded parameter x[10] and time as x[11]). Kicks off
point 3 from morning review.

Next up: scram X_entry expansion (morning point 2) — LOCA scenario
+ union of mode reach envelopes.

results/

Output artifacts from reach / barrier / validation runs. All files in this directory are gitignored — they're regenerated by running the corresponding script.

What lives here

Named <analysis>_<variant>.mat (MATLAB v7 format, read/written via Julia's MAT.jl for historical convenience — switching to JLD2 is a deferred item, see journal/ for context).

Generated by (as of 2026-04-21):

`reach_operation_result.mat`	`code/scripts/reach/reach_operation.jl`

Consumed by:

code/scripts/plot/plot_reach_tubes.jl — tube overlay figures.
app/predicate_explorer.jl — live per-halfspace margin rendering.

Why this directory exists

reachability/ used to hold both source-of-truth specs (predicates.json, README, WALKTHROUGH.md) and ephemeral reach results. Mixing stable vs.\ regenerated content made it hard to tell which was which at a glance. Split: reachability/ = specs + docs, results/ = outputs.
