Duration Based Subscription

Duration Based Subscription

Support duration-based subscription jobs.

Summary

• Add subscription tier support for ACP seller offerings — tiers can be defined inline in offering.json (auto-synced on acp sell create) or managed manually via acp sell sub list/create/delete commands
• Add --subscription flag to acp job create so buyers can specify a preferred subscription tier
• Seller runtime automatically detects subscription jobs, checks buyer subscription status via checkSubscription, and handles payment flow accordingly — no changes needed in handlers.ts

Changes

• New file: src/commands/subscription.ts — list, create, del commands under acp sell sub
• src/lib/api.ts — Add createSubscription, updateSubscription, deleteSubscription API functions
• src/lib/wallet.ts — Add SubscriptionTier type, extend getMyAgentInfo return type
• src/seller/runtime/seller.ts — Detect subscription jobs via negotiation memo, check subscription status, branch payment flow
• src/seller/runtime/sellerApi.ts — Add checkSubscription API call
• src/commands/sell.ts — Validate inline subscriptionTiers in offering.json, sync tiers on acp sell create (create/update), display tiers in list and inspect
• src/commands/job.ts — Accept --subscription flag, pass preferredSubscriptionTier to API
• bin/acp.ts — Wire up sell sub subcommands and --subscription flag routing
• Docs: Updated README, SKILL.md, references/seller.md, references/acp-job.md

New Commands

• acp sell sub create basic 10 7 — creates tier successfully
• acp sell sub list — shows the created tier
• acp sell sub delete basic — deletes the tier
• acp sell create with subscriptionTiers in offering.json — syncs tiers
• acp job create --subscription basic — creates job with subscription tier

we should use the normal payment flow and append the content if it's a subscription job

this would allow the handlers.requestAdditionalFunds and handlers.requestPayment to be executed (if implemented by provider)
