feat(inbox): consolidate three inbox workflows into one engine

I merged process-inbox, monitor-inbox, and inbox-zero into one inbox.org engine. A shared core (value gate, skeptical review, disposition ladder, reply discipline, capture-guard, priority-scheme check) holds the logic that used to be duplicated and cross-referenced across the three files. Each mode (process, monitor, roam) references the core by name instead of restating it.

Every trigger phrase still works, now routing to a mode, so there's nothing to relearn. I added the interactive auto inbox zero mode: ask for an interval, run roam mode on /loop, acknowledge-only on an empty cycle, surface a find to a queue gated on a yes. The fully-unattended /schedule pass stays vNext, tracked separately.

I repointed every live caller (INDEX, protocols, startup Phase C, wrap-up Step 3, triage-intake, broadcast) at inbox.org and its modes, then deleted the three old files. triage-intake and no-approvals stay separate by design. The value gate, dispositions, capture-guard, and reply discipline all behave as before.

Built from the Ready spec. Workflow-integrity and sync-check pass on both the canonical and mirror trees, the stale-reference grep is clean, and the full suite is green.

Source-aware rejection flow: handoff rejections write a response back via =inbox-send= naming the failed gate question and any reconsideration condition.

-- =monitor-inbox.org= — the cadence + act-vs-file + reply layer over process-inbox: "monitor the inbox" runs a pass now then loops process-inbox every 15 min; gates on a clean tree + green suite at both ends; in no-approvals mode auto-executes only agreed + quick + solo items (else files or parks); also the ambient =inbox-status= task-boundary check and the reply-to-sender discipline.

-- =inbox-zero.org= — route the *global roam inbox* (=~/org/roam/inbox.org=) to owning projects by =<project>:= heading prefix. Distinct from =process-inbox.org= (the project's own =inbox/= dir). The current session claims only its own prefixed items, files them into =todo.org=, removes them from the shared inbox, and leaves foreign/unowned items. Every scan reports the total item count plus how many appear related to this project. v1 is single-destination (prefix-claim only); domain-aware whole-inbox routing is deferred. Called read-only from startup (count + offer) and as a wrap-up Step 3 sub-step.

+- =inbox.org= — one engine for the project's inbox surfaces, with the shared value gate / skeptical review / disposition ladder / reply discipline / capture-guard / priority-scheme check in one place, plus thin per-surface modes. *Process mode* evaluates each project-local =inbox/= item against the three-question value gate, then implements / folds / files / defers / rejects per source (auto-invoked by startup when inbox is non-empty). *Monitor mode* runs process mode now then loops it every 15 min, gating on a clean tree + green suite and adding the act-vs-file + no-approvals-execute + reply discipline. *Roam mode* routes the global roam inbox (=~/org/roam/inbox.org=) to owning projects by =<project>:= prefix (read-only nudge at startup, sweep at wrap-up). *Auto inbox zero* runs roam mode on an interactive =/loop= at a Craig-chosen interval. Distinct from =triage-intake.org= (external accounts), which stays separate.
