code-modernization: add topology viewer screenshot to README
Rendered from AWS CardDemo (the public mainframe sample app) by running
/modernize-map end to end and capturing the resulting TOPOLOGY.html.

code-modernization: vendor d3, viewer robustness, status command, pipeline fixes
Viewer (assets/topology-viewer.html):
- inline a minified d3 subset (hierarchy/pack, zoom, selection,
  interpolateZoom, ease; ISC license) instead of loading from a CDN —
  the page is now fully self-contained and works on air-gapped networks
- handle duplicate node ids (unique-suffix; edges bind to the first
  occurrence) and store parent references directly, fixing
  level-of-detail and selection corruption with messy generated data
- share one reveal rule between drawing, edge culling, and hit-testing
  so edges no longer draw into collapsed containers
- pre-bucket edges by kind and keep a per-node adjacency map; the
  hover/selection pass no longer scans every edge each frame
- cancel in-flight fly-to animations when a new one starts; clamp
  fly-to zoom to the zoom extent; derive max zoom from the smallest
  leaf so deep estates stay reachable
- render dead-end candidates (new deadEnds field) with a dashed
  outline and a sidebar badge
- clicking a node during a flow walkthrough exits the walkthrough;
  search results clear on selection and Escape; surrogate-safe label
  truncation; clearer stats line; explicit empty-topology message

Commands:
- new /modernize-status: read-only progress report — artifact inventory
  with timestamps, staleness flags, secrets-hygiene checks, next step
- map: deadEnds in the topology schema; datastore names must be logical
  identifiers with credentials stripped from URLs/DSNs
- brief: read topology.json + .mmd files (not the interactive HTML);
  staleness check against inputs; effort unit aligned to person-months
- transform: secret-safe characterization-test prompt; diff -y fallback
  when delta is missing; credential-safe diff selection
- reimagine: target vision is everything after the first argument (was
  silently truncated to one word); masking rules in spec/scaffold/
  handoff prompts
- brief/transform/reimagine: human-approval gates phrased as explicit
  stop-and-wait instead of 'enter plan mode'
- preflight: delta in the tool table; brief added to the verdict list
- README: preflight/status in the workflow; legacy/ deny list also
  covers Write; plugin + marketplace descriptions updated

code-modernization: harden topology viewer and template injection
Fixes from an adversarial review of the new viewer:

- pin d3 to 7.9.0 and load it via dynamic import with an explicit
  error panel when the CDN is unreachable (previously a blocked CDN
  produced a silent dark page — a real concern for restricted networks)
- coerce ids/names/loc at intake: a single missing name or non-numeric
  loc previously threw inside the render loop or propagated NaN through
  the pack layout, blanking the canvas with no error
- normalize flows/steps/edges defensively (null entries, missing steps,
  numeric ids vs string lookups)
- mirror the level-of-detail reveal rule in the hit test so clicks
  can't select nodes that aren't drawn
- scope the Escape shortcut so clearing the search box doesn't reset
  the viewport; set zoom clickDistance(4) so trackpad jitter doesn't
  swallow selection clicks
- round canvas backing-store size (fractional devicePixelRatio caused
  a reallocation every frame on 125%/150% display scaling)
- modernize-map: use braced ${CLAUDE_PLUGIN_ROOT} so substitution
  actually happens, assert the injection marker exists in the template,
  and correct the documented failure mode

code-modernization: interactive topology map, preflight command, persona flows
modernize-map previously rendered the call graph and data lineage as
static Mermaid diagrams, which become unreadable once a node has ~10+
edges — exactly the shape of real legacy systems. It now builds an
interactive viewer from a shipped template (assets/topology-viewer.html):
a zoomable circle-pack of domains/modules sized by LOC, rendered to
canvas with level-of-detail reveal, dependency edges with per-kind
toggles, search with fly-to, a per-node detail sidebar, and a flow
walkthrough mode. Small domain-level .mmd exports remain for docs.

- topology.json now has a documented schema (hierarchy + edges + entry
  points + observations + flows) consumed by the viewer
- map traces 2-4 business flows anchored to personas (claimant,
  operator, auditor), each step in plain business language mapped to
  the modules that implement it; the viewer plays them as numbered
  paths
- brief gains a Business Walkthroughs section connecting each persona
  flow to the phase that replaces it
- new modernize-preflight command: detects the stack, checks analysis
  tooling, smoke-compiles a real source file with the legacy toolchain,
  inventories missing copybooks/descriptors/binary-only artifacts, and
  writes a per-command readiness verdict
- transform now verifies legacy + target toolchains before its plan
  gate instead of failing at test time
- README: commands updated, optional-tooling section reframed as 'what
  to give Claude'
