[docs] Document hookForceClaim for World authors and spec version 8

[pranaygp]

Follow-up docs for PRs that landed in the last day. #4193 shipped its user-facing docs and #4353 added cross-links; this fills the World-author and reference gaps that were left.

createHook({ experimental_force: true }) (#4193)

• worlds/upgrading-to-v5: hookForceClaim in the capabilities list, plus a "Hook token takeover" row describing what a World must guarantee before advertising it
• worlds/building-a-world: hookForceClaim in WorldCapabilities; mintedSpecVersion() now stamps 8 by default (was documented as 7)
• configuration/runtime-tuning: WORKFLOW_SEALED_LOG=0 stamps runs below spec 8, so their hook tokens can't be taken over
• world/storage: claimedFrom in the Hook type table
• workflow/define-hook: create() takes the same options as createHook(), including experimental_force

Nothing more needed for #4326, #4124, or #3908.

No backport to stable for 98234f3 (AI decision).

This commit documents new capabilities (hookForceClaim, createHook({ experimental_force: true }), Hook.claimedFrom, and the bump of the default minted spec version to 8) that were introduced by feature PR #4193 on main. Documenting new capabilities is feature work, not a documentation correction, and the described behavior does not exist on stable, so backporting it would misdescribe the maintenance line.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:
