Bug Fixes

zfb build no longer fails with owned island build token cannot resolve external relative import when a symlinked package that resolves outside the project root (a nested pnpm-style layout or a workspace: sibling) ships an unexported, never-imported file whose relative import does not exist, such as a raw eject template. Files reached only by walking a linked package now skip unresolvable relative imports while their bytes still feed the build token; plugin and tsconfig alias targets and declared root files still fail on a broken import. Present since v3.0.0 (#4060; ba559c43, 04c8e2e8).
The declared-root audit plan label in zfb css / wind source planning is preserved when the project or temp directory sits behind a symlink, such as macOS /var → /private/var (#4054; 8b0b64a5).
zfb dev no longer goes silent after a watcher handoff when a known page is created or a page with an invalid island registration is edited and then recovered: the tick now reports its outcome, normalizes known page creates, and rediscovers unregistered pages after modified recovery edits (#4056; 3120ecc8, fe2ac5e8). This fix is verified on Linux CI; its macOS confirmation is deferred to #4090.
