feat: advisory message appended to block output (#362)

Browse Source 
* docs(specs): add custom block messages and package blocklist spec

* docs(specs): add custom block messages and package blocklist implementation plan

* feat(config): add blocked_packages list and custom block messages

* feat(audit): add package_blocklist_blocked event and blocklist model

* feat(proxy): block blocklisted packages in the policy gate before analysis

* feat(guard): block blocklisted packages before trust skip and analysis

* feat(ui): render blocklist blocks and custom messages, fix silent-mode block output

* feat(proxy): append custom messages to malware and go-cooldown block bodies

* test(proxye2e): cover blocklist enforcement and custom block messages

* docs(specs): remove spec and plan documents

* refactor: drop guard-flow blocklist enforcement and trim docs

Guard mode is being deprecated; the blocklist is enforced in proxy mode
only. Remove the trusted_packages mirroring references outside the docs.

* refactor(config): consolidate blocklist and block message under top-level block section

Replace dependency_cooldown.message, malware.message and blocked_packages
with a single block section: block.message is appended to every block
output regardless of which control blocked, and block.packages is the
package blocklist.

* fix(ui): render block.message as info note with clean spacing

* fix(ui): indent wrapped continuation lines in block reasons and messages

* update config template

* refactor(config): replace block section with top-level advisory_message

Remove the package blocklist (will be implemented as part of policies in
the future) and replace block.message with an optional top-level
advisory_message appended to every block output.

* chore(config): move advisory_message near top-level scalar configs in template
