chore(session): pre-stage signal-mcp config + snapshot session-context

This commit is end-of-day housekeeping for the rulesets session that
ran 2026-05-28 through 2026-05-29.

mcp/servers.json gains the signal-mcp stdio entry pointing at the
locally-cloned rymurr/signal-mcp install at ~/.local/share/signal-mcp/.
The entry uses Craig's primary +15103169357 as --user-id, which will
need updating to the Google Voice number once that signal-cli
registration lands (TODO scheduled today). The configuration is
staged but not registered. The make install-mcp pipeline was
interrupted earlier by the GPG pinentry (Craig on vacation, away
from desk). Running make install-mcp at the desktop with the GPG
passphrase will complete the registration.

.ai/session-context.org captures the live session narrative covering
the no-approvals batch (6 :quick:solo: TODOs), the codex backlog
triage, the page-signal infra, the voice profile Phase 1 plus Phase
2, the SKILL.md / voice-profile.org structural split, and the inbox
processing pass. No wrap-up performed. The session-context stays
under that name pending the wrap-it-up workflow when Craig is back
at the desk.

The substantive work in this session shipped across many prior
commits, each with its own focused message.
