CLI fix: create command missing creationFee as msg.value

[realproject7]

From E2E test #644 / agent-os #327

Bug

`plotlink create` reverts with `MCV2_Bond__InvalidCreationFee` on mainnet because the CLI doesn't read or pass `creationFee()` from MCV2_Bond as `msg.value` in the `createStoryline` transaction.

Fix

In `packages/cli/src/create.ts` (or the SDK client if still used internally):

1. Read `creationFee()` from the MCV2_Bond contract before calling `createStoryline`
2. Pass it as `value` in the `simulateContract` / `writeContract` call

Branch

`task/660-cli-creation-fee`

Self-Verification (T3)

• Run `plotlink create` on Base mainnet with donor wallet — succeeds without revert
• Verify storyline appears on plotlink.xyz after indexing
• Hide test storyline after verification
• `npm run build` passes
