chore(deps): finish toolchain upgrades and drop dead weight (#644)

* chore(deps): finish toolchain upgrades and drop dead weight

pino 9 to 10, @types/node 24 to 26, oxlint 1.73 to 1.87, knip 6.26
to 6.39, turbo 2.10 to 2.11. Narrow engines to supported majors
(22/24/26; vitest 5 refuses Node 25). Scope no-var-requires off for
Electron CJS hooks and fixtures.

Remove TypeDoc: incompatible with TypeScript 7 at install and
runtime, used by nothing in any gate. Drop the dep, docs:api
workflow, typedoc.json, CI artifact step, and related docs.

Replace graphology with a local call-graph adjacency plus BFS: the
only consumer is call-path search, and graphology-types ships no
types entry for TS7 NodeNext resolution. Delete both graphology
dependencies.

Remove dead re-exports newly flagged by knip 6.39.

* chore: drop stale typedoc and replay references

Remove the docs:api release-checklist step, the orphaned docs/api
ignore entry, and the nonexistent replay glob from the adapters
project.
