v0.6.1

Patch: the agent auto-attach hook (SPEC-0073) shipped with a 10s timeout — too tight for its
first npx -y aireceipts-cli@latest run on a cold npm cache (which downloads the package,
including the @resvg/resvg-js native dep, before it can write the ref). On a fresh clone the
first push could hit the timeout and silently skip its receipt. Bumped the pre-push hook timeout
to 60s (still bounded — the push is never gated on the receipt). The SessionEnd --mini hook
timeout is unchanged (10s). No other behavior change; rendered output is byte-identical.
