Reorganise the tree into business vs frontend as separate directories:
src/core/{domain,imports,app} (was system/, imports/, app/)
src/frontends/tui/ (was tui/ + main.cpp)
tests/tui/ (the FTXUI-coupled helper test)
All cross-dir #include paths rewritten; same-dir includes untouched.
CMake: essim_core is the frontend-agnostic business library — links libzip,
pugixml and bsdl, NO GUI toolkit. Each frontend is a self-contained
src/frontends/<name>/ (own CMakeLists, toolkit, main.cpp) that links
essim_core, selected with -DESSIM_FRONTEND=<name> (default tui; 'none' = core +
tests only, no toolkit fetched). FTXUI moved into the tui frontend. Tests are
split: essim_tests links essim_core (no FTXUI), essim_tui_tests links essim_tui.
Verified: default tui build green (ctest 2/2); ESSIM_FRONTEND=none builds the
core + tests with FTXUI never fetched and no `essim` binary.

Major additions, all wired end-to-end with doctest coverage:
- Altium netlist importer (`imports/import_altium.{hpp,cpp}`): two-pass
parser for `[ ]` parts and `( )` signals; `System::Load` no longer has
the IMPORT_ALTIUM hole.
- `duplicate <src> <dst>` deep-copies a module (signals, parts, pins,
rewired signals); connections excluded by design.
- Nets (`system/nets.{hpp,cpp}`): BFS over `Connection::pin_map` to
return the transitive (Module, Signal) closure. `verify` extended with
a second pass flagging Power↔GndShield inconsistencies in bridged
nets; new `net <module> <signal>` command for inspection.
- Canonical pin names (`system/pin_name.{hpp,cpp}`): zero-padded digit
suffix lets A1 ↔ A001 pair via `IdentityTransform` and
`CheckIdentityCompatible` without losing the imported notation.
- Component classification (`system/component_kind.{hpp,cpp}`):
`Part::kind` inferred at construction from the reference-designator
prefix (longest-match: LED/TP/SW/FB/MK/MP/MH/HS/RA/RN/RP/RV first,
then R/C/L/F/D/Q/U/J/P/Y/X/S).
- Identity wiring tolerance: `CheckIdentityCompatible` accepts the
subset case (typical when one importer drops NC pins, e.g. Altium)
and surfaces orphans as an info string. `FillIdentityNCs`
materialises orphan canonical positions as NC pins on the missing
side at connect time.
- Connector layout preparation: `pin_layout(kind)` and
`FillPartFromLayout(part, kind)` stubs in `pin_role`, called from
`set-type`. Empty today; populate alongside `vpx_3u_role`.
- TUI scrollback: PageUp/PageDown step 10 lines, Home/End jump to
ends; `Print()` snaps back to the tail.
- `set <name> <value>` declares session variables; `$name` / `${name}`
expanded inside `Finalize` between canonical-form recording and the
action call — history and script-save preserve `$var` references.
- Long `source` scripts now show a centred "Computing…" modal with a
N/M progress counter. Driven by a ticker thread that posts one
paced `Event::Special` per processed line, ack'd by the main thread,
so heavy lines don't backlog ticks and freeze the counter.
