Jeremy Rose bc3545b805 Validate linked worktrees before inheriting project trust (#39616)
## Why

A checkout could point its `.git` file at a trusted repository's worktree
directory without proving that the repository had registered that checkout.
This could cause project configuration from an unrelated checkout to be treated
as trusted.

## What changed

- Verify the linked worktree's `gitdir` backlink, `commondir`, registered
  checkout, and main checkout ownership before resolving the main repository's
  trust key.
- Reject missing, oversized, symlinked, mismatched, or swapped Git metadata.
- Preserve valid linked worktrees that use path aliases, separate Git
  directories, or non-UTF-8 POSIX paths.

## Testing

Add resolver and config-loading coverage for forged worktrees, metadata races,
case-sensitive paths, moved worktrees, and host MCP startup from project config.
