fix(deps): dependency wave — 105 OSV advisories → 3 reasoned suppressions, all lanes verified on the pinned scanner

Root: overrides pin ip-address 10.3.1 (defeats BOTH nested nodes — socks'
range pull and express-rate-limit's exact 10.1.0 pin, which a top-level bump
provably cannot reach) and sharp 0.35.0 (GHSA-f88m, HIGH; transformers still
pins ^0.34 upstream — smoke-tested round-trip); marked ^18.0.11; full in-range
lockfile refresh clears hono, fast-uri, protobufjs, qs, body-parser, nanoid,
uuid, immutable and friends.

lib/diagram-render (via its own build-script contract: exact pins edited,
fresh lock, dist rebuilt): mermaid 11.16.1, @excalidraw/excalidraw 0.18.1,
@excalidraw/mermaid-to-excalidraw 1.1.2 → 2.2.2 — the 1.x line exact-pinned
mermaid 10.9.x and dragged the entire duplicate mermaid-10 advisory chain
(dompurify 3.1.6, nanoid 3.3.3, lodash-es); the bundle shrinks 9.96 → 7.59 MB
with the duplicate mermaid gone. Nested exact pins that survived get scoped
overrides (nanoid 5.1.16, lodash-es 4.18.1).

Verification: clean-worktree frozen-lockfile installs (root + nested) + the
SAME osv-scanner release the action pins (v2.3.8) with the workflow's exact
scan-args → exit 0, 'No issues found'. Smoke tests cover the override
surfaces (sharp round-trip, ip-address lockfile assertion, marked parse);
socks + diagram-drift suites already pin the rest.

Supersedes #2695 (its own lockfile kept socks/ip-address@10.2.0; @anupamme's
report credited for the parallel diagnosis).
