chore(go): wire coverage-badge action inputs

- App.Rc runs all executable files in <castle>/.homesick.d in sorted
  (lexicographic) order with the castle root as cwd
- Non-executable files are skipped
- stdout/stderr from scripts forward to App writers
- If .homesickrc exists and parity.rb does not yet exist in .homesick.d,
  a Ruby wrapper (parity.rb) is generated before execution
- Existing parity.rb is never overwritten
- Wire rcCmd in CLI with optional CASTLE argument (defaults to dotfiles)

@@ -13,18 +13,29 @@ A `### Breaking` section is used in addition to Keep a Changelog's standard sect
 
 ### Added
 
-- Native Go implementations for `clone`, `link`, `unlink`, and `track`.
+- CI validation now runs `gosec` and `govulncheck` security scanning on push and pull request workflows.
+- `cmd/homesick` now includes entrypoint-focused tests that exercise both the CLI run path and `main` process path.
+- `rc` command: executes all executable scripts inside a castle's `.homesick.d/` directory in sorted order, with the castle root as the working directory. stdout/stderr from each script is forwarded to the caller.
+- `rc` command: when a `.homesickrc` file exists and no `parity.rb` wrapper is present in `.homesick.d/`, a Ruby wrapper script (`parity.rb`) is generated automatically to preserve backwards compatibility. An existing `parity.rb` is never overwritten.
+- `exec` command: runs a shell command inside the target castle root directory.
+- `exec_all` command: runs a shell command inside each cloned castle root directory in sorted order.
+- `pull --all` support: pulls updates for every cloned castle in sorted order.
+- `rc --force` support: legacy `.homesickrc` compatibility hooks now require explicit force mode before execution.
+- Global command flags restored: `--pretend` (with `--dry-run` alias) and `--quiet`.
+- Native Go implementations for `clone`, `link`, `unlink`, `track`, `pull`, `push`, `commit`, `destroy`, `cd`, `open`, and `generate`.
 - Containerized behavior test suite for command parity validation.
 - Dedicated test suites for `list`, `show_path`, `status`, `diff`, and `version`.
 - Just workflow support for building and running the Linux behavior binary.
 - Coverage reports and badges published to shared object storage for branches and pull requests.
 - Pull requests now receive coverage report links in CI comments.
-- Manual release preparation workflow and script to bump the reported version, promote unreleased changelog notes, and create release tags.
-- Main branch validation now emits a recommended next release tag based on unreleased changelog sections, and release preparation now rejects empty unreleased notes.
-- Release recommendations now support an explicit `### Breaking` section for major-version changes that would otherwise be described under `### Changed`.
+- Automated release orchestration now runs through vociferate prepare and publish workflows.
+- `symlink` command alias compatibility for `link`.
 
 ### Changed
 
+- Release automation now uses `aether/vociferate` `prepare` and `publish` actions (pinned to `v1.0.1`) instead of repository-local releaseprep wrappers.
+- Push and pull request validation now enforce per-package coverage gates (fail below 50%) and publish package-level coverage status tables in workflow summaries.
+- Push and pull request validation now verify module hygiene (`go mod tidy`, `go mod verify`) and use a dedicated summary-file pattern with a final always-run summary step.
 - CLI argument parsing migrated to Kong.
 - Git operations for clone and track migrated to `go-git`.
 - Build and behavior workflows now produce and run the `gosick` binary name.
@@ -34,14 +45,20 @@ A `### Breaking` section is used in addition to Keep a Changelog's standard sect
 - CLI help now uses the invoked binary name (defaulting to `gosick`) in usage output.
 - CLI help description now reflects Homesick's purpose for managing precious dotfiles.
 - Release notes standardized to Keep a Changelog format.
+- `commit` command now accepts legacy positional form `commit <castle> <message>` in addition to `-m`.
+- `destroy` now prompts for confirmation by default and preserves the castle when declined.
 
 ### Fixed
 
 - `status` and `diff` now consistently write through configured app output writers.
+- `pull --all` output now includes per-castle prefixes to match behavior expectations.
+- Behavior-suite container now includes Ruby so `.homesickrc` parity wrapper execution works under `rc --force`.
 
 ### Removed
 
+- Legacy `script/prepare-release.sh` releaseprep wrapper and its dedicated script test.
 - Legacy Ruby implementation and Ruby toolchain.
+- Legacy in-repository `releaseprep` package and command implementation, now superseded by the standalone `vociferate` tool.
