fix(newos4): js keeps its string literals — dispatcher forwards the raw command line (v4.6.130)

_parseArgs() treats quote characters as delimiters and drops them, so every string literal in a
js expression died before eval: `js "abc".toUpperCase()` reached the module as
`abc.toUpperCase()` → ReferenceError: abc is not defined. Same for `js import('fs')` →
`import(fs)`. Found while verifying the v4.6.128 console fix
(plan 2026-10-29_112000-newos4-parseargs-strips-js-string-literals.md).

- terminal.js: checkAndRun() records the untokenised line (`_currentRaw`), _dispatch() forwards it,
  dispatchCommand(cmd, args, rawText) passes it to the module. Security classification still runs
  on the tokenised form, and pipes/AI/script-runner calls pass nothing, so they behave as before.
- console.js: `js` evaluates _expr(args, rawText) — the raw remainder. `node -e` deliberately does
  NOT: the tokenizer already keeps `'…'` inside `"…"`, and the raw form would hand eval the string
  literal `"import('fs')"` instead of the import (caught by the live probe, not by review).
  js-run keeps tokenised paths.
- modules/test/test-parse-args.js: tokenizer table (records the deletion as the current contract),
  dispatcher plumbing asserts, _expr cases, and the user-visible paths. 27 assertions.
- module-loader.js + main.html + bundle: v4.6.130 (129 was minted, then console.js changed again —
  re-minting so no cached client keeps the intermediate).

Verification
  node modules/test/test-parse-args.js        -> 27/27 pass
  same file against HEAD sources (git show HEAD:...)  -> TypeError: _expr is not a function (RED)
  scripts/lint-no-undef.py terminal.js console.js     -> clean, 122 cross-file globals
  core-bundle.js rebuilt from HEAD sources + this patch in /tmp/iso (the working tree carries
  another session's uncommitted ollama-manager.js `_httpError`); diff vs HEAD bundle = 14 lines,
  all mine. critical-ext-bundle.js byte-identical.
  Live page v4.6.130 (real executeCommand, output captured):
    js "abc".toUpperCase()        -> ABC
    js 'a b'.split(' ').length    -> 2
    js JSON.stringify({a:1})      -> {"a":1}
    js 6*7                        -> 42
    js import('fs')               -> red "Failed to resolve module specifier 'fs'" + Node-builtin hint
    node -e "import('fs')"        -> same error + hint (was printing the expression as a string)
    echo "two words"              -> two words
    js-run /nope.js               -> js-run: /nope.js: No such file
    unhandledrejection count      -> 0

The sibling's parked terminal.js hunk (BillingModule registry entry) was stashed for this commit and
is restored in the working tree afterwards; it is not part of this change.
