`System.*` and the newer `Os.*` (added in #21) both covered the environment
around the game, with four members (`arg`, `arg_count`, `env`, `exit`) lowering
byte-for-byte identically and the standard streams overlapping in concern. That
is a user-facing ambiguity (`System.env` vs `Os.env` are indistinguishable) and
a drift hazard (two copy-pasted codegen paths).
Make `Os.*` the single canonical environment/process namespace and retire the
overlapping `System.*` members:
- Remove `System.{arg, arg_count, env, exit, stdout, stderr}` from the namespace
dispatch (selfhost/emit_expr.ludic). Use `Os.arg`/`Os.arg_count`/`Os.env`/
`Os.exit` and `Os.stdout_write`/`Os.stderr_write` instead.
- `System.*` now covers only its unique low-level surface: the raw file handles
(`file_open/read/write/seek/tell/close`), `read_char`, and `run`.
- The bare `arg`/`exit`/`getenv`/`file_stdout`/`file_stderr` intrinsics stay —
they are the primitive layer the self-hosted compiler itself uses; only the
redundant *namespaced* sugar is gone.
- Docs: drop the six retired `docs/language/system/*` pages, retune the section
blurb, update inventory.json and the LSP signature table.
- Secondary finding from the issue: cross-link `Text.upper`/`Text.lower`
(ASCII-only) to `Unicode.upper`/`Unicode.lower` (full Unicode case mapping).
Reseeded; C-free bootstrap fixpoint holds. All suites green (56 test / 29
selfhost / 29 test-tools); docs cover every implemented feature (291 ns-methods).

Expand the abbreviated string type and its conversion builtin to the full
word everywhere:
str -> string (the immutable-string type)
str(x) -> str -> string(x) -> string (the stringify builtin;
what `{…}` interpolation calls)
Types are recognized by identifier, and llty maps both spellings to LLVM
`ptr`, so this is an atomic source rewrite: type annotations, the Ludic
type tags, the builtin name/dispatch, and the interpolation desugar, plus
the grammars, LSP, docs (type-str -> type-string, fn-str -> fn-string), and
inventory. int/bool stay (universally accepted, like Math).
Reseeded; C-free fixpoint holds; all suites green (45/24/29); site + check.py OK.

Implement the bulk of the namespaced-stdlib proposal (workshopsoft/ludic#2):
156 namespace methods across Math, Text, List, Ease, Collide, World, Net,
Sys, Save, Mem, extended Screen, Color functions, extended Random, and Time.
All deterministic fixed-point; self-hosting (C-free bootstrap fixpoint holds).
Compiler (selfhost/):
- Math.*: sqrt/sin/cos/tan/atan2/asin/acos (fixed-point runtime prelude —
bit-by-bit isqrt, 256-entry interpolated sine table, Ross atan2), plus
hypot/dist/dist2/deg_to_rad/rad_to_deg/posmod/wrap/ping_pong/snapped/
move_toward/smoothstep/lerp/remap/sign/floor/ceil/round.
- Text.* (complete): upper/lower/trim/repeat/pad, split/join/replace,
and the libc-backed queries.
- List.* (complete): insert/remove_at/remove/sort plus the earlier ops.
- Ease.* (in/out/in_out/back/bounce) and Collide.* (rects/point_rect/
circles/rect_circle).
- Phase 3: World/Net/Sys/Save namespaced over the bare builtins (byte-
identical IR) and Mem.* (bytes/words/copy/fill/peek/poke).
- Screen.* extended (line/circle/fill_circle/triangle/fill_triangle via new
runtime primitives; sprite/sprite_scaled aliases), Color.* functions,
Random.* (value/int/sign), Time.* (frame/delta/elapsed/now — new
game-loop frame counter).
- Fix a lexer bug: fixed-point literals with >4 fractional digits overflowed.
Docs & tooling:
- 129 new per-symbol doc pages; gen.py made data-driven (namespaces
discovered from the docs, no hardcoded list); new check-impl.py enforces
that every implemented namespace method / keyword / type / phase has a
doc page, wired into `x test-tools`. Document the previously-undocumented
keywords (break/continue/where/entry/new/public + and/or/not tokens).
- LSP: namespaced signature help (ns_method_sig) covering every namespace.
Tests: 12 new self-host/regression tests + a golden render for the drawing
primitives. All suites green (selfhost 21, regression 45, tools 29).
