Update go-releaser heading with experimental notice

[masih]

To avoid confusing validators and to test the whole process more in terms of templating, make it clear that statically linked binaries are experimental and use a H2 header.

PR Summary

Low Risk
Release note templating only; no build, binary, or runtime behavior changes.

Overview
Updates the GoReleaser release header so GitHub releases no longer open with a version-only # Sei {{ .Tag }} title.

The header now uses ## Experimental Pre-built Binaries, signaling that attached statically linked seid artifacts are experimental. Checksum instructions and the Docker image pointer are unchanged.

One-line cosmetic change to the goreleaser release-notes header (H1 tag title → H2 "Experimental Pre-built Binaries"); the change is correct and self-consistent with name_template and mode: append. Only nits remain, plus a note that the Cursor review pass produced no output.

Blockers

• None at the file/PR level.

Non-blocking

• The Cursor second-opinion review file (cursor-review.md) is empty — that pass produced no output, so this review reflects Claude + Codex only. Codex reported "No material findings."
• PR description says the change is partly "to test the whole process more in terms of templating," but the diff removes the only template expression ({{ .Tag }}) from the header. Templating is still exercised via name_template, so nothing is broken — just a minor mismatch between the stated rationale and the diff.
• No CHANGELOG entry. The closely related goreleaser release-notes change (#3857) was recorded under ## v6.6 in CHANGELOG.md; for consistency this backport-labelled PR could add a line under ## Unreleased → ### Improvements. Skip if release-notes cosmetics are intentionally excluded from the changelog.
• 1 suggestion(s)/nit(s) flagged inline on specific lines.

[nit] The stated goal is to "avoid confusing validators," but the heading now asserts "Experimental" without saying what that implies. Consider one qualifying sentence so a validator reading the release page knows what to do with it — e.g. "These statically-linked binaries are experimental; for production use the Docker images below." As written, the reader learns the status but not the recommendation, and the body text underneath is unchanged from when the heading was just the tag name.

The H1 → H2 demotion itself is right: name_template: '{{ .Tag }}' already supplies the tag as the release title, so the old # Sei {{ .Tag }} duplicated it, and H2 nests correctly under the auto-generated body that mode: append appends to.
