build: generate everything into build/, keep src/ free of generated files

src/ carried 8.4 MB of build output: the genome header, the javascript vm and
its layout, and the language-server image, plus a second copy of the extension
server under editors/vscode/server/. none of it is source.

- move the genome from src/core/genome.h to build/core/genome.h and compile with
  -Ibuild/core; `make all` bootstraps one when it is missing
- write genome.json, layout.ts, layout.js and lsp.json to build/js/
- compile tinyvm.ts to build/js/, typed by a tracked src/js/layout.d.ts so the
  vm needs no generated file beside its source
- build the wasm server into build/editors/vscode/server/ and stage the whole
  server into editors/vscode/server/ only while mkvsix.sh packages it
- redirect the test suite, image_run.js, tinyvm.sh, tinyvm.bat, test_win.ps1 and
  the baremetal build at the new paths, and add make lspimage and make vsix
- stop tracking every generated file

also fix a build blocker: lookup_raw compared skind against K_VAR, which was
never declared, so `make genome` could not run at all. the guard is about
emitted program globals, which are K_GVAR and K_GARR.

tests/test.sh -q reports 159 passed and 21 failed both before and after this
change; every failure is pre-existing and comes from the checked-in genome being
stale relative to src/, plus the bootstrap above.
