Paul BakausandClaude Fable 5.1 0547ed6a63 reorg C: the open Rust runtime joins this repo as one Cargo workspace
The engine no longer lives in a separate repo. `crates/` is a snapshot of the
open crates (foundation, core, common, context, live, hook, skills, comp,
comp-verbs, html, browser, detect, cli) plus `Cargo.lock`, taken as a git
archive of the engine repo at the commit that finished the boundary split.
None of that repo's history comes with it, and none of it should: the closed
half stays private.

The closed half is the rule engine. It ships as a prebuilt native archive per
target, `libimpeccable_detector.a`, published as a `detector-v<X>` GitHub
Release on this repo. `crates/core/build.rs` resolves and links it three ways:
`IMPECCABLE_DETECTOR_LIB=<dir>` for a local detector build, else the
`~/.impeccable/detector/<version>/<target>/` cache, else a download verified
against its `.sha256` sidecar. `crates/core` is a thin shim over a three-symbol
C ABI; nothing above it knows the boundary exists.

What changed versus the engine repo copy:

- Every crate manifest moves from `license-file.workspace` to
  `license.workspace` (this workspace declares Apache-2.0), and the workspace
  gains the `postcard` dependency the boundary encoding needs.
- The launcher contract test reads `skill/scripts/impeccable{,.cmd}` instead of
  a sibling `launcher/` dir, and `engine_binary` downloads from
  `github.com/pbakaus/impeccable/releases/download/engine-v<version>/` instead
  of the retired dist repo. No oracle golden carried the old URL, so no
  re-recording was owed.
- The tests that hunted for a public repo through `IMPECCABLE_PUBLIC_REPO`,
  `../impeccable-second` or a hardcoded home directory now resolve the root as
  `CARGO_MANIFEST_DIR/../..`, because they are in it. The env var stays as an
  override for an out-of-tree checkout.
- The in-page bundle (`detect-antipatterns-browser.js`, 2 MB of generated wasm
  glue) is no longer tracked. `crates/core/build.rs` resolves it beside the
  archive, hands the path to `impeccable_core::browser::IN_PAGE_BUNDLE_JS`, and
  live mode serves that. `scripts/check-detector-release.mjs` now requires it
  and its `.sha256` in a detector release.
- The live crate embeds `skill/scripts/live-browser*.js` and
  `modern-screenshot.umd.js` directly rather than through vendored copies, so
  the binary and the installed skill cannot drift.
- `crates/browser/assets/` (an unused second copy of the bundle) is gone.
- `tests/lib/engine-bin.mjs` also accepts `target/release/impeccable`, so a
  plain `cargo build --release -p impeccable` is enough to run `bun run test`.

Verified with the archive from a local detector build: `cargo test --workspace`
267 pass, oracle 795 pass / 0 fail / 0 missing, `bun run build` clean, the
default suite green, and the launcher's `engine-probe` handshake answering
through `skill/scripts/impeccable`.

//! Triage D2: the URL engine must scan passively — with `Page.setBypassCSP`
//! removed, a strict-CSP page's CSP-blocked inline scripts must NOT run during
//! a scan (they did under the old `setBypassCSP(true)` setup).
//!
//! This serves a page with `Content-Security-Policy: script-src 'self'` and an
//! inline `<script>` that a strict CSP blocks. The script, if it ran, would set
//! a global and mutate a marker element. The test drives the browser exactly as
//! the engine does (its page setup no longer bypasses CSP) and asserts the side
//! effect did not fire. Skips cleanly with no installed browser.
