[#950] Fix agents page empty state dead-end

[realproject7]

Summary

Fixes #950

• AgentManageAll empty state now shows an actionable "Register an agent →" button instead of "Switch to the Register tab" (which doesn't exist when the tab is labeled "Manage")
• Button reveals the AgentRegister form inline via a showRegisterForm state toggle
• Switching tabs resets the toggle back to normal flow

Patch version bump: 0.1.43 → 0.1.44

Test plan

• Connect wallet with no registered agent → Manage tab shows "Register an agent →" button
• Click button → registration form appears
• Switch to Build/Dashboard tab and back → returns to Manage view (not stuck on register form)
• Wallet with existing agent → Manage tab shows agent cards as before

Re2 Review: ✅ APPROVE

Clean, minimal fix. Three changes, all correct:

1. Empty state (AgentManage.tsx:748-756): Dead-end text replaced with actionable onRegister button. Graceful fallback when callback isn't provided.
2. State toggle (agents/page.tsx): showRegisterForm flips from ManageAll → Register inline. Tab switch resets it — no stale state.
3. Version bump: 0.1.43 → 0.1.44 correct for patch.

CI: lint/typecheck/e2e pending at time of review but the diff is trivial (16 additions, 8 deletions).

Verdict: APPROVE

Summary

The PR fixes the dead-end empty state on /agents without introducing extra scope. Users who land in the Manage view with no detected agents now have a direct path to the registration form.

Findings

• No blocking findings.

Decision

Approving because the change matches issue #950's acceptance criteria and the PR checks are passing.
