Michał Pierzchała e832325e87 refactor(substrate): split host mechanics into @agent-device/host-kit capability ports (#2088)
* refactor: split generic host mechanics into @agent-device/host-kit (#2082 W1)

The shared src/utils closure that blocked the platform-family moves lands
on declared owners: generic host mechanics form a new private
@agent-device/host-kit package between kernel and capture-kit, and
capture-kit keeps capture, snapshot, and recording behavior, depending on
host-kit for the mechanics it needs. tar-stream and yauzl move with the
archive code.

Every seam's exported subpaths are pinned in package-boundaries.test.ts,
the layering model ranks the new zone, R13's allow-list names it, and each
seam carries an exact eager-closure row. ADR-0019's substrate amendment
describes the layout.

Tests that mocked two of the moved modules separately became duplicate
same-seam vi.mock factories, where the second silently replaced the first;
those are merged, and the mocks that production code reaches past are
pinned at their injection points instead.

* refactor(host-kit): one narrow capability port per export

The four technical barrels (exec/fs/values/request) grouped by category
rather than by capability, so a consumer needing one mechanic evaluated
unrelated ones. Each export is now a single capability over the host
machine: command, process, diagnostics, retry, archive, file, request,
version. A port re-exports only what a consumer of that capability uses,
and every port carries its own eager-closure row.

Most of the old values barrel was never host mechanics. Pure record
readers, config-source values, result text, memoization, async scoping,
coordinate validation, and device-scope parsing touch no process, file, or
environment, so they join kernel's other primitives instead.

Closures fall accordingly: capture-kit's png-worker-client from 20 to 10,
png-resize from 28 to 18, session-teardown from 79 to 68, and the CLI from
386 to 380.

* fix: point the Swift parity comment at the real TS twin and test

The W1 move rewrote this citation to packages/contracts/src/mobile-snapshot-semantics.ts,
which does not exist: the module went to capture-kit while isTapPointInsideViewport itself
went to packages/contracts/src/snapshot-visibility.ts. The TS test line was left pointing at
the pre-move path. Both now resolve.

* fix: repoint comment citations at the homes this refactor moved them to

The W1 move left ~20 comment citations pointing at src/utils/*.ts and
src/request/*.ts paths that no longer exist. Each now names the capability
port that owns the symbol, which survives further file moves:

  exec -> host-kit/command          host-process, owner-identity -> host-kit/process
  diagnostics -> host-kit/diagnostics   atomic-file, process-lock -> host-kit/file
  retry -> host-kit/retry           request progress/cancel -> host-kit/request
  version -> host-kit/version       ttl-memo, source-value, parsing, device-isolation,
                                    keyed-lock, success-text -> kernel subpaths

Comment-only; no closure, budget, or behavior change. ADR citations are left
as written, being dated records of the decision rather than live references.

Stryker's sandbox rewrites tsconfig `extends`/`references` through the classic TypeScript API, which the repo's TypeScript 7 native package no longer exposes (`ts.parseConfigFileTextToJson is not a function`). Our tsconfig has neither extends nor references, so there is nothing to rewrite — skipping the preprocessor is exact, not a workaround for a real dependency. The behaviour relied on is that the preprocessor no-ops when the file is absent: see packages/core/src/sandbox/ts-config-preprocessor.ts (https://github.com/stryker-mutator/stryker-js/blob/master/packages/core/src/sandbox/ts-config-preprocessor.ts) and https://stryker-mutator.io/docs/stryker-js/configuration/#tsconfigfile-string.
