Complete CLI and local developer workflows #124

Description

Improve day-to-day development through reload, manifest discovery, logging controls, adapter discovery, consistent exits, scaffolding, local stores and adapter test dispatch.

Main already scaffolds provider-wired projects and supplies credential-free local stores. The CLI still lacks reload orchestration, a list-adapters command and a test command; generic manifest loading, logging filters and exit contracts retain gaps described in the child issues.

Steps to reproduce

1. Inspect the CLI command enum, generator and local store wiring.
2. Compare the remaining child scopes with the current serve and command-dispatch paths.

Expected behavior

A developer can scaffold, run, inspect and test an application locally through predictable CLI behavior.

Impact

Several routine workflows still require external scripts or knowledge of implementation details.

Proposed fix

Track the remaining #125–129 and #132 work here; record #130 and #131 as delivered. Keep new CI scaffolding #161 and the existing local-provision epic coordinated without duplicating completed functionality.

Done when

• Reload, manifest search-up, development logging, adapter listing, exit contracts and test dispatch are accepted.
• Template scaffolding and credential-free local stores remain supported.
• Help/docs describe the actual serve command and any dev alias explicitly.
