chore(deps): upgrade docs toolchain to TypeScript 7

[drewstone]

Remaining problem

Runtime, Eval, Knowledge, Bench, and their direct Interface contract now use Agent Interface 0.36.0. PR #630 proved that cohort. Older transitive Interface copies from Materialize and Sandbox remain tracked in #623.

The only work left here is TypeScript 7 support. TypeScript 7.0.2 is published, but TypeDoc 0.28.20 currently declares support only through TypeScript 6.0.x.

Completion

• wait for a TypeDoc release that supports TypeScript 7 without a fork or peer override
• upgrade TypeScript, TypeDoc, and the Markdown plugin together
• pass frozen install, typecheck, tests, packed package checks, Bench, docs:api, and docs:freshness

Checked on 2026-07-27 against current npm metadata and Runtime main 2e1016f6510f13e137c114d17acdd83766278285.

Disposition on 2026-07-28: keep open, blocked on upstream support.

Fresh npm metadata:

• typescript: 7.0.2
• typedoc: 0.28.20, peer range ends at TypeScript 6.0.x
• typedoc-plugin-markdown: 4.12.0, peer range typedoc@0.28.x

Runtime main@073551d0 still pins TypeScript 6.0.3 and TypeDoc 0.28.20. Do not add a peer override or fork. The completion criteria in the issue remain current.

Disposition against origin/main@15f1ee3e5caae0a953e92645748b30ae30a2b07f, published Runtime 0.109.0, and current npm metadata: keep open.

The upstream prerequisite remains false. TypeScript latest is 7.0.2; TypeDoc latest is 0.28.20 and its peer range ends at TypeScript 6.0.x; typedoc-plugin-markdown@4.12.0 accepts TypeDoc 0.28.x. Runtime main still pins TypeScript 6.0.3, TypeDoc 0.28.20, and the Markdown plugin 4.12.0. No implementation PR tied to #625 has merged.

Remaining exactly: wait for upstream TypeScript 7 support without a fork or peer override, upgrade all three packages together, then pass frozen install, typecheck, tests, packed-package checks, Bench, docs:api, and docs:freshness.

Fresh 2026-07-29 disposition: keep open on the upstream dependency.

Current npm metadata is TypeScript 7.0.2, TypeDoc 0.28.20 with a peer range ending at TypeScript 6.0.x, and typedoc-plugin-markdown@4.12.0 requiring TypeDoc 0.28.x. Runtime 0.109.2 did not change this toolchain. A TypeScript 7 upgrade would still require an unsupported override or fork, so the completion steps in this issue remain current.
