W104 (partial) — Release 0.11 Compatibility Sweep (#447)

* W104 (partial) — compatibility sweep: manifest, replay oracle, pack/smoke

Extends the W96.2 regression-evidence manifest (regressionManifest.test.ts)
with the two in-repository hosts (MCP server, static ASP.NET host) and the
packed public consumer surface (consumer-smoke/), verified to fail for the
right reason when a named file goes missing (W104.1, partial — campaign/save
enumeration is not yet covered).

Adds build/Test-CompatibilitySweep.ps1, composing typecheck/lint/test, a
local run of the replay regression oracle against v0.10.0's own fixtures
(the same REPLAY_BASELINE_DIR mechanism ci.yml's release-tag-replay job runs
automatically at tag time — W104.4, verified: 29 replayed, byte-identical),
and the packed-tarball consumer smoke (W104.6, verified: clean tarball, no
workspace resolution, ./authoring exports exercised) into one documented,
locally runnable command (W104.7).

W104.2 (campaign-builder additive-field golden diffs), W104.3 (0.10 save
fixture corpus + migration replay), and W104.5 (unified text
client/MCP/static host/Adventures integration against one pinned archive)
remain unmet: each needs new fixture corpora or cross-repo companion
coordination out of proportion for this session, same reasoning W103.7 used
for deferring /kit-sync.

* verify: record W104 gate report (10 passed, 5 environment-gated did-not-run)

+<#
+.SYNOPSIS
+Runs the 0.11 release-candidate compatibility sweep (W104) from a clean checkout.
+
+.DESCRIPTION
+Composes, into one documented command, the checks that together decide whether
+the current tree can call itself a compatibility candidate against a prior
+release tag (W104.7):
+
+  1. typecheck, lint, and the full test suite from src/engine -- includes the
+     W96.2/W104.1 regression-evidence manifest (regressionManifest.test.ts),
+     which fails the moment a named suite, fixture, host, or packed-consumer
+     file goes missing.
+  2. The replay regression oracle (07-replay.md), run locally against the
+     baseline tag's own committed fixtures and outcomes -- the same
+     REPLAY_BASELINE_DIR mechanism .github/workflows/ci.yml's
+     release-tag-replay job runs automatically on every release tag push.
+     Running it here proves W104.4 (byte-identical replay) without waiting
+     for a tag.
+  3. npm pack, with the same tarball-content assertions ci.yml's engine job
+     makes (no src/, no tsconfig, no test artifacts, dist/ present) --
+     W104.6's clean-pack half.
+  4. The packed-tarball consumer smoke (consumer-smoke/), installed with no
+     workspace resolution back into src/engine -- W104.6's install/compile/run
+     half, exercising the public and ./authoring entry points together.
+
+This script does not replace ci.yml's two jobs; it reproduces their combined
+result on demand, from any machine, without needing a release tag pushed
+first -- exactly the gap W104 exists to close before 0.11 is cut.
+
+.PARAMETER BaselineTag
+The prior release tag to compare replay fixtures against. Defaults to the
+most recent 'v*' tag reachable from HEAD, matching ci.yml's own
+"previous tag" resolution.
+
+.PARAMETER SkipConsumerSmoke
+Skip the packed-tarball consumer-smoke step. For a fast local re-run of the
+engine-only checks; CI always runs the full sweep.
