build(deps): bump github.com/open-policy-agent/opa from 1.15.2 to 1.17.1

[dependabot]

Bumps github.com/open-policy-agent/opa from 1.15.2 to 1.17.1.

Release notes

Sourced from github.com/open-policy-agent/opa's releases.

v1.17.1

This release uses the latest version of Go (1.26.4) to build OPA, fixing stdlib vulnerabilities in code that OPA's HTTP handler and crypto builtins use:

• https://pkg.go.dev/vuln/GO-2026-5039
• https://pkg.go.dev/vuln/GO-2026-5037

It is otherwise the same code as v1.17.0.

Note that users building their own OPA binaries and images already control the Golang version, so this is not relevant for them.

Miscellaneous

• build: bump go 1.26.3 -> 1.26.4 (authored by @​srenatus)

v1.17.0

This release contains a mix of new features, performance improvements, and bugfixes. Notably:

• A new future.keywords.not import that adds improved semantics to the not keyword.
• Rule Labels in Decision Logs
• Published json schema for IR and bundle manifest
• Dropped automaxprocs and x/net dependencies

Improved Negation Semantics (#8387)

This OPA release introduces a new future.keywords.not import that fixes a long-standing semantic issue with negation in Rego.

Without the import, the compiler expands a negated composite expression like not f(g(input.x)) into a series of sub-expressions evaluated before the not:

__local0__ = input.x
g(__local0__, __local1__)
not f(__local1__)

If any sub-expression fails — for example, input.x is undefined or g produces an undefined result — the entire rule fails rather than the not succeeding. This is unintuitive: the user's intent is "the condition does not hold," but an undefined intermediate value causes a silent failure instead of the expected not result.

With import future.keywords.not, composite-expression negation wraps the full compiler expansion in an implicit body:

not { __local0__ = input.x; g(__local0__, __local1__); f(__local1__) }

... (truncated)
