feat(inbox): poll-and-retry the capture-guard instead of bouncing

When a roam edit hits a live org-capture, the guard used to bounce the caller right away (surface to the user, or skip the cycle) even though the capture is usually a few seconds of mid-finalize that clears on its own. capture-guard gets a --wait poll mode: it re-checks every ~10s up to a budget (default 30s, each sleep capped so a short --wait never overshoots), returns the instant the capture clears, and reports blocked only at the deadline. The no-capture common case still returns instantly without sleeping.

Roam mode now uses --wait on every write, and the per-caller fallback fires only after the wait: an interactive run surfaces, the auto /loop defers to the next cycle (the loop cadence is the retry), wrap-up skips and self-heals.

Surfaced live this session: a transient capture blocked a roam reconcile and had cleared a minute later. Covered by three new bats cases (instant-when-safe, timeout-when-blocked, target-after-flag).
