docs(keycloak-session-store): import the session-storage lab as a new project

The keycloak project ended with four open questions that design could not
settle. A two-VM lab was built to answer them by measurement, and this is
that material: 26 experiments, 125 raw command outputs, 22 browser captures.

Follows the import procedure in README.md.

  source/     the originating repository verbatim — 78 documents, 28 SVGs,
              8 manifests, plus .source-revision recording the commit
  final/      the SSOT
    document.md   729 lines written from the 29 experiment documents, not
                  concatenated: what was predicted, what was measured, and
                  where the measurement itself was wrong
    evidence/raw    125 outputs, flattened to <experiment>__<file> because
                    the originals collided (01-baseline.txt appeared three
                    times) and the audit only globs the top level
    evidence/meta   one per raw file; command and exitCode are null and the
                    README says why rather than inventing them
    evidence/browser  22 captures
    assets/       three diagrams through techviz
    .techviz/     their VizSpecs

A separate project rather than an addition to keycloak: the B-layer answers
that project's four questions, but the A, C and D layers are about cluster
failure, SSO and operations, and one document.md should hold one subject.
The four question records there can point here through 관계.

Recorded rather than papered over: only three of the 28 diagrams were
remade. The repository forbids hand-drawn SVG and forbids titles inside the
canvas; all 28 originals carry both, so converting them is redrawing, not
reformatting. They stay in source/ and the gap is written into the document.

verify-pipeline.py passes. audit-records.py reports no issues.

+$ sed -n '89,99p' app-bootstrap/src/main/java/dev/caskeleton/bootstrap/CaSkeletonApplication.java
+   * <p>The Fileserver admin package is here for a different reason: those routes belong to the
+   * management context, and a component scan that also found them would publish the management
+   * plane on the public connector — the exposure the separate context exists to remove.
+   *
+   * <p>The web platform's error, budget and operation packages are here for a third reason. Their
+   * advices and controllers need beans that only exist when the corresponding platform
+   * auto-configuration is active, and a component scan finds them regardless — so an all-off or
+   * partially configured deployment failed to start on an unsatisfied dependency rather than simply
+   * not installing the control. Ownership by auto-configuration is what ties a control's presence
+   * to its dependency's.
