Mindrealm v1 revision r9 -- PHLEGM v9 r29 Compiler UI parity

Base: Mindrealm v1 r8 (2026-10-12).
Reference: PHLEGM v9 r29 (2026-10-16).

Shared scripts are byte-identical with the PHLEGM v9 r29 sources:
- tools/Compiler-UI.ps1
- tools/Mindrealm-Compiler.ps1 (same bytes as PHLEGM-Compiler.ps1)
- Mindrealm-Windows-Compiler.bat (same bytes as PHLEGM-Windows-Compiler.bat)
- Mindrealm-Linux-Compiler.sh (same bytes as PHLEGM-Linux-Compiler.sh)
- tools/bootstrap/Install-and-Compile.ps1
- tools/bootstrap/Windows-Install-and-Compile.bat
- tools/bootstrap/Linux-Install-and-Compile.sh
- All three external bootstrap archive members match those same embedded scripts.

Behavior inherited from r29:
- Auto-compile 20 seconds after opening the Compiler UI.
- Compile button bypasses countdown.
- Window close before compilation exits automatically.
- Window close or Exit while compiling requests Cancel, waits for logging/finalization, then exits.
- Explicit Cancel leaves UI open; successful build history remains intact.

Mindrealm remains Mindrealm v1 (not PHLEGM): its custom target matrix,
build parameters, independent settings and upstream install path stay in JSON.
The project-specific tools/Build-Mindrealm-v1.ps1 remains unchanged because
it compiles a distinct program; it is not a shared/compiler-UI engine.
Other runtime files and data have not been changed.

Verification: shared-script SHA256 hashes, canonical ZIP structure, shell syntax,
configuration schema, and JavaScript lifecycle simulations. Run the included
PowerShell tests and native build for full integration validation.
