fix(agents): restore server mode + prompt_async supervisor launch from 9bbec0e6

Restores the working OpenCode server mode + curl-based async supervisor
launch functionality from commit 9bbec0e6 (2026-04-02) and updates it for
the current 13-supervisor architecture.

Changes applied to 7 agent files (938 insertions, 221 deletions):

1. product-builder.md: Restored from 9bbec0e6 and updated for 13 supervisors
   - Full bash permissions for curl/sleep
   - Server URL: http://localhost:4096
   - Launch via POST /session + POST /session/:id/prompt_async
   - Session resume (adopts existing [CA-AUTO] sessions)
   - Added ca-test-infra-improver and ca-project-owner to launch sequence
   - Updated concurrent worker calculations (~5N + ~8 singletons)

2. issue-implementor.md: Restored curl-based worker dispatch
   - 10-second polling loop with bash sleep
   - Worker sessions via prompt_async
   - Session resume for existing workers

3. ca-continuous-pr-reviewer.md: Restored curl dispatch pattern
4. ca-uat-tester.md: Restored curl pool mode
5. ca-bug-hunter.md: Restored curl pool mode
6. ca-test-infra-improver.md: Added self-dispatch permission
7. ca-session-cleanup.md: Restored utility agent

Architecture: 5 pool supervisors (N workers each) + 8 singleton supervisors
= 13 total supervisors running async via prompt_async.

Replaces the broken prompt_async implementation from commit 074c472e that
removed supervisors from task permissions without working server launch.

To use: Start OpenCode with --port 4096, then launch product-builder.

Refs: commit 9bbec0e6 (working version), commit 074c472e (broken version)
