e2e-platform

Run, fix, or extend the Skaile platform e2e suite. Three modes: run executes the existing suite with pre-flight checks (stale-service guard for post-pull stale bundles, stale-deps guard for lockfile drift, seed sync, proxy slot health), failure-mode diagnosis, and auto-recovery (kill stale skaile-serve subprocesses, sync seed data, restart stuck proxy slots); fix triages each failing test as a stale test (the product changed on purpose) vs a real regression (the product broke), then repairs stale tests (rewrite to the new shape / delete a removed feature / skip with a reason) while STOPPING and escalating regressions to the human — never weakening an assertion to force green; add analyzes a git diff, proposes a test plan, waits for explicit user approval, lives-inspects the UI via chrome-devtools MCP, then writes new specs against the existing harness in the platform repo's e2e/ directory. Use when the user says "run e2e tests", "fix the failing e2e tests", "the e2e suite is red", "add e2e coverage for <feature>", "write e2e tests for my PR", or similar.
