docs / build-and-deploy (push) Successful in 2s
`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).

Returns a fresh string with every ASCII letter <code>A</code>-<code>Z</code> turned to lowercase; other bytes pass through unchanged. Pair it with <code>Text.equals</code> for case-insensitive matching by lowercasing both sides. This is ASCII-only — accented and non-Latin letters are left as-is; for full Unicode case mapping use <code>Unicode.lower</code>.
