Add movement and Traitor practice to the introduction

Expand /learn from five lessons/three exercises to seven lessons/five exercises. Movement practice uses shared board geometry and occupancy rules to teach ordinary range, separate-city ornithopters, storm blocking, full strongholds, one-group movement and conserved force counts. Traitor practice uses the production combat quote for an optional post-reveal call, a declined losing plan, a sole successful call and mutual betrayal, with the existing full private Traitor inspector. The fixed opponent scenario is explicitly teaching data, not live private information or an AI match.

Migrate every v1 saved lesson to its same identity after insertion, preserving previous choices and outcomes under the existing browser key. Validate v2 movement commitments and reveal/call stages, whitelist saved fields and default only new choices. Browser testing exposed stale pre-update React state surviving hot refresh; a schema-keyed lesson remount runs the migration for development updates too. No live rules, AI strategy, room persistence or server scheduling changed.

Eleven focused cases include all 96 movement combinations against actual authoritative actions, exact force/spice preservation, sole/mutual/declined Traitor outcomes, all five old lesson mappings and malformed or impossible save rejection. Independent review found no material teaching, privacy or restore issue. Types, lint, all 4899 offline tests and production build pass on the unchanged source fingerprint. HTTP and complete-game runs were not repeated for this browser-local guidance change.

Browser checks verified range, storm and full-stronghold explanations, committed movement after refresh, private Traitor inspection, decline and successful-call outcomes, and mutual calls after a refresh at the revealed-choice stage. At a 390px viewport both new lessons fit within the 375px client width without horizontal overflow; keyboard movement selection committed four arrivals and one source remainder. Screenshot acceptance remains open. The viewport was reset and /learn retained as the deliverable.

All 1174 rooms, 2456 seats and every original recovery/entry/handover row remain unchanged. SQLite integrity and foreign keys pass. No new live room, migration, reset, restart, usage check or automation was needed. Broader curriculum, rules/mode acceptance and publication remain unfinished. The status dashboard identifies durable unattended bot recovery as the next independent backend capability; pending faction-rule questions were preserved.

 ## Current checkpoint and work
 
-Latest delivered gameplay checkpoint: `20cc605`, [Smuggler battle collection](SMUGGLER_BATTLE.md).
-Types, lint, **4,884 offline tests**, production build and **43 HTTP tests** passed.
-The surviving unmodified leader collects even after losing or capture, with saved
-settlement before Sandmaster. All 1,106 baseline rooms and 2,314 seats stayed
-unchanged; isolated checks added 34 rooms and 71 seats. No restart was needed.
-The subsequent `8f7a62c` policy checkpoint removed the usage cutoff and deferred
-AI refinement until feature completion, with three adjacent 75% win-rate targets.
-Earlier evidence remains in the [implementation history](IMPLEMENTATION_STATUS.md).
