Milestone 6: BLOCK_MAP.md signature-status column
--manifest mode's file scan is a completely separate code path from build mode (only ever walks .4th files, never the embedded PKI cert or font capsule) -- extended it to accept the same optional --sign-key <path> prefix build mode already has, factoring the key-loading code into a shared load_sign_key(), so the manifest can report real per-capsule signing status without touching or requiring a rebuild of capsule_generated.c. New "Signed" column on the capsule summary table: yes/no when --sign-key was given, n/a (with an explanatory footnote) when it wasn't -- never a bare blank that could be misread as "unsigned". Makefile.starkernel's manifest-generation call site now passes the same SIGN_KEY_ARGS the real build uses, so capsules/BLOCK_MAP.md reflects this machine's actual signed state by default. Verified: clean compile, BLOCK_MAP.md correctly shows "yes" for all 31 tracked capsules on a real signed build; a quick amd64 boot (no kernel code touched, host tooling only) confirmed no regression. This closes every open Milestone 6 item except magic-number content-type detection (shared with Milestone 4, not started) and the hard-refuse flip (deliberately deferred). Documented in FABRIC-3.md.

the Makefile invokes `mkcapsule` twice per build for two different purposes (once to emit

optional `--sign-key <path>` prefix as build mode (factored the key-loading code, previously

inline in build mode's arg parsing, into a shared `load_sign_key()` used by both) so the
