Add ProjectV2 status update tools (list, get, create) (#1987)

* Add ProjectV2 status update tools (list, get, create)

Closes #1963

Add three new individual tools and wire them into the consolidated
project tools for managing GitHub ProjectV2 status updates:

- list_project_status_updates / projects_list: List status updates for
  a project with pagination, ordered by creation date descending
- get_project_status_update / projects_get: Fetch a single status
  update by node ID
- create_project_status_update / projects_write: Create a status update
  with optional body, status, start_date, and target_date

New GraphQL types and queries (statusUpdateNode, statusUpdatesUserQuery,
statusUpdatesOrgQuery, statusUpdateNodeQuery) support both user-owned
and org-owned projects. The CreateProjectV2StatusUpdateInput type is
defined locally since the shurcooL/githubv4 library does not include it.

Also includes quality improvements discovered during implementation:

- Extract resolveProjectNodeID helper to deduplicate ~70 lines of
  project ID resolution logic shared between addProjectItem and
  createProjectStatusUpdate
- Add client-side YYYY-MM-DD date format validation for start_date
  and target_date fields before sending to the API
- Fix brittle node type check in getProjectStatusUpdate that relied
  on stringifying a githubv4.ID and comparing to "<nil>"
- Refactor createProjectStatusUpdate to accept typed parameters
  instead of raw args map
- Add deprecated tool aliases for all three new individual tools
- Add ProjectResolveIDFailedError constant for consistent error
  reporting

Test coverage includes 21 subtests covering both user and org paths,
pagination, error handling, input validation, field verification, and
consolidated tool dispatch.

* Fix projects_get required params and harden status update tools

Loosen projects_get schema to only require "method", since
get_project_status_update only needs status_update_id and never uses
owner or project_number. Also use pointer types for optional
statusUpdateNode fields, add owner_type validation for list/create
status updates, clamp negative per_page values, and fix
resolveProjectNodeID to return "" instead of nil on error.

* Resolve conflicts

* Update doc

* Update aliases

* Dont update tool renaming docs
