error (spec 4.1.5, b.1.9)
track linited per local alongside the ownership state; snapshots, exit records and joins carry it, and a join keeps a local set only when every reaching path set it. x = e, a declaration initializer, &x (out-parameter), a full array initializer, or using an aggregate as an address set a local; field and element writes do not set the aggregate. while/for bodies that may run zero times do not count; do/while does. compiler, runtime, std, actor and lsp sources initialize the locals the rule flagged; zc0 accepts = {} brace lists (zeroed). tests: tests/errors/uninit_*.zc, tests/conformance/4-statements/uninit_*.zc

defer expr; and defer { ... } register code that runs when the enclosing
block ends: at the end of the block, and at return, break and continue
that leave it. the tokens are kept at the defer and compiled again at each
exit (block_close, body, kw_return, kw_break, kw_continue), newest first,
before the block's variables are released, so the analyzer sees a deferred
rt.free(p) as the transfer of p where it runs. names mean what they meant
at the defer; values are read when it runs. return, break and continue
inside a deferred statement are errors, reported once. works in unchecked
code and closures (own base per function context).

src/compiler/compiler.zc is now twelve files under src/compiler/, listed in
order in src/compiler/parts. cat of the parts in order is byte-identical to
the old file, so every compiler and image except the language server's is
unchanged. no function was edited.
consumers read the list: the makefile, bootstrap-check, genmap (which still
writes one compiler.zc into a generated map directory), tinyvm.bat,
test.sh, test_win.ps1 and the lsp drivers. the language server embeds each
part and serves them joined as the one document tinyvm:/compiler.zc.
