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).

run-only images
- hover: a symbol from an embedded library source (tinyvm:std.zc, tinyvm:icon.zc) was
looked up only in the document; look it up by its qualified name in the library source
(hover_embedded_sym), and render a method found that way by its line (bs_hover).
- std.capture: allocate one word more than the 256 it holds, so end() terminates inside the buffer.
- a bare call to a static function of the enclosing struct resolves like a bare struct constant
(mstruct is set for every non-generic struct's methods); the struct's own wins over a global.
- run.zc declares main untyped (fn main();), so a run-only image accepts int, void or untyped main
with both compilers.

array instead of a heap list the analyzer rejected.

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.

- delete TASKLIST.md and docs/design/handoff.md; the handoff content lives in README.md
- move docs/BOOTSTRAP-OWNERSHIP.md to docs/history/ and index it in docs/history/README.md
- point ONBOARD.md, docs/BORROW.md and the ticked TODO.md item at the new path
- ONBOARD.md section 9 no longer mentions TASKLIST.md
- ONBOARD.md section 3 and 4 markers are now `// ...` (line comments lost their colon)
verified from a clean build: make clean, make (fixpoint 376903 words), the
section 0-7 commands (section 4 after the marker fix), and the rejection suites. make check was
started but did not complete (stopped before it finished).

TODO.md ticks the items verified done (namespaces, actor and icon libraries
and their coverage, the genome embed, the bootstrap ownership limits, the
docs and fixtures sweep) and lists everything still open, including the
newly requested language features, sorted easiest first.
the compiler no longer names actor: file libraries for suggestions come from
src/lib/modules.txt, and lib.name before its include reports the missing
include. icon gains fixtures for reading globals while stepping and for
begin_function on a non-function, and the suite checks that nothing the
compiler reads by default mentions actors. bf.zc, the web sample and std's
capture example use qualified runtime names; LEARN.md uses build/bin paths.

actor and icon
two items. first, documentation, examples, learn entries, history notes and
expected-output fixtures still carry bare runtime builtin names from before the
namespace work; the suite gates the snippets it exercises but not the rest.
second, actor and icon each need their own accept, reject and regression
coverage once they land, including the constraint that no actor code is
reachable from the compiler by default.

`make genome` cannot complete: the second bootstrap stage runs the lifetime
checker over the compiler's own source, which reports 8 errors, and mkgenome
then reads the diagnostics as an image.
the two limits are that an owned value held in a local has no move into another
local — every accepted move originates at a call, so the free-then-replace rule
only applies when the replacement comes from a call result — and that a local
cannot be lent to a global, so redirecting the output stream at a scratch buffer
needs a module-level variable.
neither limit accepts an unsafe program; both refuse correct ones, so this is a
completeness gap rather than a soundness failure. document the affected code, the
diagnostics, what was tried and how each attempt failed, and a proposal.
add src/tools/bootstrap-check.sh, which rebuilds both bootstrap stages and prints
the compiler's diagnostics on its own source instead of the word dump.

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.

Compiler and VM
- make every memory map limit dynamic and adjustable at both build time and
runtime, including compiler tables, stacks, and every execution region
- reserve and grow tables, operand and return stacks, frame segments, and
image-building output without relocating live code or globals
- rename i/o and string helpers consistently (puts -> put_s, putn -> put_n,
scat -> cat_s) across compiler, runtime, examples, tests, and docs
- recast and consume values assigned to globals from inside functions
- allow fixed and const together, add typed closure returns (fn:t(...)),
multi-include syntax (include rt, run, core;), and recurse type inference
- never infer string literals as word, anywhere, as argument, variable, or
return type
- draft docs/BORROW.md: a borrow checker less intrusive than Rust's but more
intelligent
LSP and editor integration
- require explicit includes and give every toolchain area its own namespace
(rt, lsp, run, core)
- hover for built-in types, inferred types, values known at hover time, array
and pointer lifetime/size, library names in include statements, and inferred
lifetimes with explanations
- honor /* */ comments as documentation for variables and arguments, and stop
misattributing section headers or trailing comments as variable hints
- stream diagnostics and cancel stale requests on change
- jump to definition and references, including cross-file
- quick fixes with automatic library import, and namespace completion
Hints and diagnostics
- render hints as blue squigglies by default, with hints on/small/off per file
- suppress magic-number hints via a preceding /* */ comment, and say so
- warn on unused arguments; allow multiple _ discards in parameters, pattern
matching, and tagged enums, warning if a _ is actually used
- rewrite hint and comment prose in professional compiler-doc register
Libraries
- add icon.zc: run-time self-modification, find/replace syntax, type and block
edits, and step-through inspection of locals and globals
- add actor.zc: async actors with Actor<I,O>, implicit this, spawn/recv/send,
injected into the compiler machinery at include time rather than built in
Tooling and docs
- reorganize sources, tests, and designs into subdirectories
- unify windows entry points in tinyvm.bat and add a matching tinyvm.sh
- add --help across the toolchain
- polish the learning guide, stdlib docs, and design notes
Tests
- add accept, reject, and regression coverage across the compiler, LSP,
- runtime, icon, actors, threads, formatting, and the toolchain contracts,
plus fuzzers and property tests
