skillscript-runtime v0.22.1

Upgrade impact: none (additive)

• Allowlist denial messages now tell agents to escalate, not self-edit. When a skill hits an off-allowlist shell binary or filesystem path, the runtime's remediation (ShellBinaryNotAllowedError, FilePathNotAllowedError) and the shell-binary-not-allowed lint rule previously read as an operator runbook — "add it to SKILLSCRIPT_SHELL_ALLOWLIST in your .env, then restart." Returned to a connecting agent through the MCP error, that reads as an instruction: the agent edits .env to self-grant the capability, defeating the operator boundary. The messages now lead with an agent-facing "stop — this is a human-operator boundary; ask the operator, don't edit config yourself," with the wiring how-to clearly labeled operator-only (and a pointer to blocked_shell_attempts as the operator's review surface). Allowlist enforcement itself is unchanged.
• CLI reference accuracy. The README + landing-page CLI table dropped three commands removed back in v0.2.1 (register-trigger / unregister-trigger / list-triggers) and a dead run alias, added init / list / approve / reapprove, and now mirrors the CLI's own command order.
• Quickstart restructured around the human/agent division of labor — the human installs, configures, and wires the MCP; the human and agent author the first skill together — and the dashboard step is corrected (it's a blocking foreground server, so the browser is opened separately).
• .env.example trimmed to what each setting does (the security rationale moved to the adopter playbook), and its example port corrected to 7878.
