/**
 * High-level helper for opening a sim session from a `mikro sim *` command.
 *
 * - Long-lived commands (`sim dev`, `sim repl`) pass `claim: true` to write
 *   the pid file and kill any predecessor.
 * - Short-lived commands (`sim deploy`, `sim test`, `sim env`, `sim profile`,
 *   `sim clean`, `sim reset`) pass `claim: false` (the default) to refuse if
 *   a sim is already running.
 *
 * Loads the project's `mikro.config.ts` (if any) to resolve the sim section,
 * then connects via `connectSim`.
