feat(plugins): unify lifecycle hooks and await worktree initialization (#8081)

* refactor(plugins): make lifecycle hook timing explicit

Use one registration method and subject.operation.step names so plugin authors can read whether an operation waits. Preserve old registrations through a single SDK adapter and keep timing and payloads unchanged.

* fix(plugins): align hook notes and example fixtures with release contracts

Keep the changelog inside its versioned beta entry for app parsing. Run current plugin examples against the checkout version so their declared requirements remain valid.

* docs(plugins): align translated hook dependency guidance

* fix(plugins): align hook exports and release documentation

* feat(plugins): use lifecycle positions and await worktree initialization

* test(plugins): cover first-agent worktree initialization

* test(plugins): verify rollback against workspace catalog entries

## Lifecycle hooks
Server entries register lifecycle observers with `server.on()` and request transforms with
`server.before()`. The [public reference](../public-docs/plugins/reference.md#lifecycle-hooks)
owns callback shapes, ordering, and failure behavior. `agent.create` edits the agent's saved
configuration; `agent.session_open` contributes launch-only `env`, `tools`, and `mcpServers`,
re-derived on each open and following the plugin's lifecycle. See
[Inject MCP servers](../public-docs/plugins/reference.md#inject-mcp-servers) for choosing the hook.
`plugin-examples/lifecycle-logger` registers all
eleven hooks; `plugin-examples/lifecycle-actions` demonstrates common automation callbacks.
Session-open hooks also [attach tools to individual agents](../public-docs/plugins/reference.md#attach-tools-to-agents),
as shown in `plugin-examples/agent-tools`. The agent manager stamps their metadata per session;
executable definitions stay in the plugin process.
Server entries register async handlers with `server.addHook(name, handler)`, returning a cleanup
function. Names follow `subject.operation.position`, ending in `before` or `after`. Waiting is a per-hook
registry property, independent of position. The [hooks reference](../public-docs/plugins/hooks.md)
owns payloads, ordering, failure behavior, and examples. `agent.create.before` edits saved
configuration; `agent.open.before` contributes launch-only `env`, `tools`, and `mcpServers` on
every open. Executable tool definitions stay in the plugin process; only metadata crosses the boundary.
Emit from the operation owner, not a client subscription. Provider history replay must not trigger
live hooks. Observers must not be awaited inside agent mutations: a callback can send a prompt or
answer a permission through its own daemon session. Awaiting it there deadlocks that command.
