The workflow checked a hard-coded TOKEN_EXPIRATION_DATE of 2025-12-01.
That date has since passed, so DAYS_LEFT is now negative and the
"-le 7" check is permanently true, causing a fresh
"YAKBOT_GITHUB_TOKEN Expiration Alert" issue to be filed every day at
midnight. The token itself is no longer needed, so delete the workflow
rather than refresh the date.

All functionality of tfproviderdocs has been superseded by
github.com/YakDriver/swissshepherd. Announce deprecation across every
surface a user, contributor, or downstream tool is likely to read:

- README.md: prominent ⚠️ Deprecated banner above the title.
- AGENTS.md: matching banner for contributors and AI agents.
- CHANGELOG.md: dated "Deprecated — 2026-06-11" entry.
- main.go: package-level "// Deprecated:" doc comment, plus a
  printDeprecationNotice helper invoked at startup that writes a
  banner to stderr (keeps stdout clean for CI parsers).
- go.mod: canonical Go module deprecation comment block above the
  module directive, so "go list -m -u" and "go get" surface a warning
  to consumers (https://go.dev/ref/mod#go-mod-file-module-deprecation).

No functional changes to the check command itself; existing tests
still pass.

Add a doc.go to each subpackage (check, check/contents, command,
markdown, version) carrying the canonical Go package doc comment plus
a "Deprecated:" paragraph. Picked up by go doc, pkg.go.dev, and gopls
hovers, so any (rare) library importer of these packages sees the
deprecation in their tooling. Complements the existing module-level
deprecation in go.mod and the package doc on main.go.
