fix(release): suppress wish GHSA alias in grype, fold rc tags into launch notes

The existing .grype.yaml ignore listed the wish SCP traversal only by CVE
id; grype's db now matches it as GHSA-xjvp-7243-rg9h and ignores are
exact-id, so the rc.2 scan gate tripped on an already-triaged finding.
List both ids. Vulnerable SCP middleware is never compiled in; real fix
is the charm v2 stack migration (#126).

cliff.toml ignore_tags folds rc tags into the next real release so
v0.1.0's notes cover full history instead of commits-since-rc.2.
