chore: drop the Signal triage-intake plugin

Remove the triage-intake Signal source plugin and de-list Signal from the engine's plugin enumeration. I'm rebuilding the Signal client (signel + signal-cli) from scratch, so the plugin would scan against an unstable client. The signal MCP server and its README setup stay. Re-add the plugin when the client is stable.

 ⚠ *THE #1 FAILURE MODE — read this twice.* Globbing only =.ai/workflows/= and silently missing every project plugin. If you skip =.ai/project-workflows/=, the sweep runs with *half its sources* and Craig never learns what it dropped — the omission is invisible, because a missing source looks identical to a quiet source in the output. There is no error, no empty block, no warning. The sweep just lies by omission. *Glob both directories. Always.*

 Craig, via the work project's same-day handoff: "we only need to report if anything's changed when we do triage intake." Sweep summaries report deltas only — a new invite, a new/moved/cancelled event, a new message needing attention. Unchanged sources get no block (the "Calendar — quiet" roll-call is retired), and an all-quiet sweep renders as a single "HH:MM sweep: no changes" line. Failures keep their loud banner (never folded into the no-change line) and the suggested-actions line stays when actions are queued. Same ruling: the telegram plugin's dev-community group traffic is dropped from reports entirely unless Craig asks (see that plugin's 2026-06-11 note).
 
 **** 2026-06-10: Loud failure surfacing (Phase C item 0 + Common Mistake 9)
-Craig: "highlight any failures in daily triage loudly. I get important communication from all these channels." Trigger: the 2026-06-10 sweep shipped with Signal silently missing — a standalone receive hung on the account lock while the signel daemon owned it, and the failure looked identical to a quiet source. Failures now lead the summary in a ⚠ SCAN FAILED banner; the signal and telegram plugins' failure paths point at this rule.

 **** 2026-05-26: Refactor into engine + source plugins
 Split the monolithic workflow into a source-agnostic engine (this file) and per-source plugins named =triage-intake.<source>.org=. The engine carries the anchor/sentinel logic, the four-bucket model, the Phase A-D orchestration, the todo.org persistence convention, and the exit criteria. Each source's scan/classify/render/action knowledge moved to its own plugin. General plugins (personal-gmail, personal-calendar, cmail, github-prs) live in =.ai/workflows/= and are template-synced; project-specific plugins (a work project's Linear, work Gmail, work Slack, enterprise PRs) live in the project's =.ai/project-workflows/= and are never synced. Phase 0 globs *both* directories — the loud requirement, because missing the project dir silently halves the sweep. Naming convention: first dot is the engine/plugin boundary, deeper dots reserved for sub-adapters. This removed all DeepSat/Linear specifics from the engine; they become work-project plugins.
