actions/workflow: bracket-quote non-ident keys in diagnostic paths (S41a-L6)

Pre-L6, an env entry with a dotted key (e.g. {"weird.key": ...}) produced
diagnostic paths like 'env.weird.key' — ambiguous between the
single key 'weird.key' and a nested env.weird.key. Authors reading
admin-actions-parse output had to deduce the boundary.

joinPath helper renders identifier-shaped keys unbracketed
(parent.child) and bracket-quotes anything else
(parent["weird.key"]). Wired into parseEnv where env names are
unconstrained YAML — the worst offender. Other callers can adopt
incrementally.

Local pathIdentRe rather than reusing the L2 polish-bundle's
canonical identRe so this cleanup PR is independent of #67. Once
both land we can dedupe.
