Levi Neuwirth d5d75e63ed fix(persistence): symlink confinement, real test-inertness, view_top restore
Addresses the PR #98 review:

- HIGH symlink escape: resolve() did only a lexical starts_with, so a
  base/autosave symlink -> /tmp/out let state.write("autosave/x") write
  outside the state dir. Now every existing component the key adds under
  base is lstat'd and a symlink (live OR broken) is rejected; base itself
  may still be a symlink (dotfile-managed ~/.local/state). Unix symlink
  escape test added (live + broken + plain-subdir-ok).

- MEDIUM integration-test state leak: the state/history dir wiring moved
  out of EditorState::new() into EditorState::install_state_dirs(),
  called only by the real entry points (editor::run, run_daemon). Unit
  AND integration tests construct EditorState directly, so they never
  configure a real dir -> default-on recentf/saveplace write nothing to
  ~/.local/state/pmacs during cargo test. The inertness test now asserts
  a bare new() leaves StateDir unconfigured (direct proof).

- MEDIUM saveplace never recorded view_top: exposed the missing
  pmacs.editor.view_top() getter (set_view_top existed but no getter, so
  the Lua stored 0). saveplace now records+restores the viewport;
  acceptance asserts view_top restores, not just the cursor byte.

- MEDIUM/LOW relative XDG_STATE_HOME / PMACS_STATE_HOME: a relative
  value rooted state at a cwd-relative pmacs/... (same footgun class as
  the empty case). Both are now required absolute; relative values are
  ignored (XDG falls through to HOME). Test added.

- LOW trailing blank line at recentf.lua EOF (git diff --check).
