fix(#1472,#1454): workstream-aware health paths; exclude active worktree from W017 (#1483)

* fix(#1472,#1454): validate health workstream-aware paths; exclude active worktree from W017

#1472: cmdValidateHealth now uses planningRoot(cwd) for shared-root files
(PROJECT.md, config.json, MILESTONES.md) and planningDir(cwd) for
workstream-scoped files (ROADMAP.md, STATE.md, phases/). Previously a
single planningDir() call was used for all paths, causing false
E002/E003/E004/W003 when GSD_WORKSTREAM is set.

#1454: W017 no longer fires for a stale worktree whose path equals or is
an ancestor of process.cwd(), preventing advice to remove the active
session's own worktree.

Regression tests added for both bugs; all 40 existing health tests pass.
