v0.3.1

Added

• Fit score bands and apply/skip verdict thresholds in search profiles (## Fit Score Bands in each profile); job-tracker:fit now outputs a structured Verdict + Recommendation based on profile thresholds (defaults: strong apply ≥45/60, apply with tailoring 35–44, low ROI <35).
• Migration mechanism for protected-zone evolution: CLI seeds missing files on init and update; job-tracker:health applies idempotent in-file migrations from migrations/<version>.md with confirmation; version markers config/.installed-version (CLI) and config/.migrated-version (health); works in plugin and workspace mode.
• migrations/0.3.1.md — first migration: adds ## Fit Score Bands to existing profiles, seeds candidate/application-answers.md in plugin mode, updates config/paths.md references.

Fixed

• Partial migration failure no longer bumps config/.migrated-version; health stops on first failed step and reports the exact failure so re-runs are safe.
• Seed steps skipped because source is missing are treated as failures (not satisfied); version marker is not bumped.
• bin/job-tracker.js: unused readFileSync import removed; seedIfMissingEntries now creates parent directories before copying.
