feat: grow memory limits, add icon/actor libraries, overhaul LSP diagnostics

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

-/* machine map, in words. the default has the code area, the compiler tables,
-   the genome and the stacks first (PW words in all) and the heap last: it
-   starts at PW and grows at run time, up to MW words of memory. MW is the
-   host's memory size; the array behind it is untouched until the heap grows
-   into it. a smaller board is a different build: src/tools/genmap writes a
-   directory whose memmap.h and genome agree, and the C cores are compiled
-   against that directory. do not edit the numbers by hand in one file only.
-
-   include genome.h before this header when both are in the translation
-   unit. the linked image's GORG then wins; it has to be the same value
-   this header would have defined.
-
-   PW is the first word past the initial stacks. emitted code can add heap
-   segments, and native code-address tables grow with those reservations.
-   MW bounds data addresses. a fixed map (HEAP_GROW 0) has MW == PW.
-
-   DSLIM and RSLIM are the interpreter's stack checks. a straight-line
-   block can push about 1024 words after the check, which is why the data
-   limit sits 1100 words above DSLO. the genome's prologue checks the current frame segment and adds another
-   segment when needed. */
