Prepare release 3.6.1

[teresaromero]

What does this PR do?

Prepares the 3.6.1 package-spec release: finalizes spec/changelog.yml, points latest-stack compliance CI at spec 3.6.1, refreshes the Go patch in .go-version, and updates AGENTS.md examples to match.

Follow-up commits on this branch also:

• Move the Fleet UI enhancements from PR #1133 into the 3.6.1 changelog (top-level sections / per-var section, and show_divider on inputs).
• Remove @skip from the OTel dynamic_signal_types dataset compliance scenarios in compliance/features/dataset.feature so those scenarios run again.

Why is it important?

Ships accumulated spec changes as 3.6.1 so integrators can depend on the released semver and CI validates the stack against that version. Re-enabling the dataset scenarios keeps compliance coverage aligned with current routing behavior for dynamic signal types.

Release contents (from spec/changelog.yml for 3.6.1)

• Enhancement: Add var_groups support to policy template and input levels in integration packages, and to policy template and package root levels in input packages. (PR #1120)
• Enhancement: Add support for named inputs in policy templates to disambiguate multiple inputs of the same type. (PR #1135) — changelog notes pending Kibana #262138.
• Enhancement: Add validation for Fleet-reserved variables (use_apm, data_stream.dataset) to enforce correct types and constraints when explicitly overridden in package manifests. (PR #1134)
• Enhancement: Add transform settings.num_failure_retries option. (Issue #1124)
• Enhancement: Add geo_shape as a valid field type for integrations. (PR #1132)
• Enhancement: Allow _dev/build/docs folder in content packages to support README auto-generation. (PR #1144)
• Enhancement: Add top-level sections list for defining named section headers, and section attribute on vars for assigning variables to a section in the Fleet UI. (PR #1133)
• Enhancement: Add show_divider optional boolean to input objects to suppress horizontal dividers in the Fleet UI. (PR #1133)

Go toolchain

Repository go directive remains 1.25.0; .go-version updated to 1.25.9 (latest 1.25 patch per go.dev). Go 1.26.x is now the latest stable minor; this PR does not bump go.mod minor. If elastic/elastic-package and elastic/integrations default branches move to 1.26, we can follow with a separate minor bump PR.

Checklist

• I have added test packages to test/packages that prove my change is effective.
• I have added an entry in spec/changelog.yml.

should we also update here to 9.5 ? or this is done after 9.4. release? cc @mrodm @jsoriano

I would keep this compliance test for now as 9.4.0-SNAPSHOT.
Related PR: elastic/kibana#261362.

Even this spec max could be used for 9.5.0-SNAPSHOT, I think I would keep it for now with 9.4.0-SNAPSHOT this compliance test.
