Merges FN-3954: adds a blocker fanout system where task staleness automatically escalates to upstream blocking tasks, with a new `blocker-fanout` core module, dashboard hooks wiring that surfaces escalation status on the board and executor status bar, and a new settings toggle to disable escalation.

Completes the FN-3166 multi-step removal of the legacy dashboard roadmap feature (backend routes, frontend API wrappers, nav state), along with FN-3792 deep-link URL support, and initial reports plugin scaffold with WhatsApp dedupe retention pruning.

Merged two features: FN-3334 introduces a new `autoReloadOnVersionChange` setting with a toggle in the Settings modal, version-check logic in the dashboard, and corresponding tests; FN-3335 fixes worktree project root resolution in `createFnAgent` and the skill resolver, with tests for both paths.
