v1.3.0 — auto-routed levels, local stats, portable export, reproducible evals

What's new

• Intensity levels with auto mode — fable-mode silently routes each task to lite / full / deep; no classification needed from the user. Pin a level in chat (fable level: deep) or persistently via ~/.claude/fable-mode/level. Misrouted tasks escalate mid-task.
• Local token stats — a Stop hook logs per-session usage to the plugin data dir (local only, no telemetry). Ask /fable-mode:fable-stats for totals and trends.
• AGENTS.md export — the same operating style, generated from the skill, for Cursor / Codex / Zed / any AGENTS.md-aware tool.
• Reproducible eval harness — evals/ ships six graded A/B tasks (root-cause instinct, triage, reuse, YAGNI, two green-test-suite traps) plus a stdlib-only runner with real token accounting, and a 14-check grading self-test.
• CI — manifests, hook scripts, skill frontmatter, AGENTS.md sync, and the grading self-test validate on every push.
• Skill additions: prompt-cache hygiene, long-session state notes, numeric uncertainty calibration.
