Adds Framework/ViewRenderer.wsc (WscMvc.ViewRenderer), loading separate
.html templates and substituting {{Key}} placeholders with HTML-encoded
values from a Scripting.Dictionary. Wires /hello through the new pipeline
(HomeController -> Application -> ViewRenderer -> Views/Home.html) while
preserving the exact pre-M4 response body, so the M1 acceptance test
doubles as a live regression check for the render pipeline.

Views/ is unreachable over HTTP by the same physical-separation guarantee
already used for Framework/ and Controllers/ (sibling of public/, never
inside it) - verified directly, not assumed.

At Daniel's explicit direction (overrides SPEC.md $5's originally fixed
tree, updated in place per AGENTS.md precedence rules):

- Default.asp + web.config moved into public/; Framework/Controllers/
  tests/tools/docs/logs are now siblings entirely outside the served root
  - physical separation, not a web.config rule, is what protects them now
- IIS site physicalPath changed to C:\Projects\wsc-mvc\public
- enableParentPaths enabled, scoped to just this site via
  `appcmd ... /commit:apphost` (writes a <location> block in
  applicationHost.config, not a machine-wide unlock of the locked
  system.webServer/asp section)
- Default.asp now uses Server.MapPath("../logs") to reach logs/
- tools/Setup-Site.ps1 automates and reconciles all of the above,
  verified idempotent (safe to re-run)
- Verified enableParentPaths does not open a client-side traversal hole:
  direct/encoded/double-encoded ../ URL attempts all correctly 404/403
- Full regression re-run (WSH, HTTP, curl+JSON self-test) all pass
  unchanged from the client's point of view
- SPEC.md, docs/ARCHITECTURE.md, docs/DECISIONS.md, docs/TEST-RESULTS.md
  updated to reflect the new structure as current, not left stale

- RequestContext.wsc: per-request path/method/correlationId/elapsed-time,
  primitive-only, no ASP intrinsics
- Application.Run(ctx, ...) centralizes expected-vs-unexpected outcomes and
  best-effort logging to logs/app.log (lock-file mutex, no ASP Application
  intrinsic available by contract)
- Fixed: Property Get requires a Class block, fails at WSC top level
  (regsvr32 exit 5) -> switched to plain Function-based getters
- Fixed: FormatNumber() leaks a locale comma into correlation ids
- Fixed: Randomize+Rnd() collide within the same clock tick -> switched to
  FileSystemObject.GetTempName()
- Verified real concurrent-logging tradeoffs experimentally (retry-the-open
  alone made it worse; lock-file mutex is correct but a full-coverage retry
  budget costs ~330ms latency, so a short budget + accepted best-effort log
  loss under heavy load is used instead)
- Investigated and resolved an inherited IUSR:(F) ACL finding under logs/
  (standard NTFS CREATOR OWNER materialization, correctly scoped, not a
  broad grant)
- All M2 SPEC/plan gate items verified PASS on real IIS; see
  docs/TEST-RESULTS.md and docs/DECISIONS.md
