- policyDecl: replace verbose on{hook,table,priority} block with
compact `hook <Hook> [priority <P>]` syntax; table is inferred
from hook, priority defaults to canonical value for that hook
- Add portforwardDecl and masqueradeDecl top-level declarations
- Add implicit injection rules for stateful/loopback/ndp to
compiler behaviour section (MVP; importable builtins deferred)
- Remove nat_prerouting / nat_postrouting from canonical policy
example (replaced by portforward/masquerade declarations)
- Update reserved keywords: add portforward, masquerade, hook (was
already reserved), priority (was already reserved); remove table
as a reserved word since it no longer appears in policyDecl
- AGENTS.md: update architecture notes, reserved-words rule, and
boundaries to reflect new declarations and compiler synthesis
