fix(init): remove triple confirm prompt on Windows CP950 terminals (#602)

Replace Rich Confirm.ask() with click.confirm() for the overwrite prompt
in 'apm init'. Rich's internal retry on encoding errors caused the prompt
to appear up to three times on Windows CP950 terminals.

 - `apm install` no longer silently drops skills, agents, and commands when a Claude Code plugin also ships `hooks/*.json`. The package-type detection cascade now classifies plugin-shaped packages as `MARKETPLACE_PLUGIN` (which already maps hooks via the plugin synthesizer) before falling back to the hook-only classification, and emits a default-visibility `[!]` warning when a hook-only classification disagrees with the package's directory contents (#780)
 - Preserve custom git ports across protocols: non-default ports on `ssh://` and `https://` dependency URLs (e.g. Bitbucket Datacenter on SSH port 7999, self-hosted GitLab on HTTPS port 8443) are now captured as a first-class `port` field on `DependencyReference` and threaded through all clone URL builders. When the SSH clone fails, the HTTPS fallback reuses the same port instead of silently dropping it (#661, #731)
 - Detect port-like first path segment in SCP shorthand (`git@host:7999/path`) and raise an actionable error suggesting the `ssh://` URL form, instead of silently misparsing the port as part of the repository path (#784)
+- Fix `apm init` showing overwrite confirmation prompt three times on Windows CP950 terminals (#602)
+- Propagate headers and environment variables through OpenCode MCP adapter with defensive copies to prevent mutation (#622)
