ui(status): unify status vocabulary, reconcile counts, and stop coloring by string-matching

Problems

1. Status vocabulary drifts from every other command: ready / not ready / fail / info here vs OK/LIMITED/EXHAUSTED in capacity and 🟢 run/🟡 wait in agent list. not ready vs fail severity (yellow vs red) is never explained.
2. Unreconcilable counts: overall says 13 ready · 1 not ready · 1 fail but the Checks table contains info rows that are excluded, so a reader cannot verify the totals against the rows they can see.
3. Long paths force the table to terminal width: the project row prints the absolute config path, so the Details column dominates column fitting and other cells get truncated with … on narrow terminals. No ~-relative shortening.
4. Empty Agents table edge: when no agents have an executable (agentEntries filters), the Agents: header, column headers, and rule render with zero rows — an empty table instead of an explanatory line.
5. Fragile color coupling: statusStyle colors by string-matching the rendered text (if (text === "ready" ...)) — the same pattern removed from capacity in 3c65af7; adding a status requires editing two functions.
6. JSON inconsistency: renderStatusReport uses raw console.log for --json while other commands use ui.text.

Expectation

• Map statuses onto the shared status model (see cross-cutting issue) with fixed severities: pass → green, warn → yellow, fail → red, info → dim; keep domain labels but derive color from a key, not from the rendered string.
• overall row counts every check including info (13 ready · 1 not ready · 1 fail · 6 info) so totals reconcile with the Checks table.
• Shorten home-relative paths (~/.ai-devkit.json); keep the absolute path only in --json.
• When there are no agent rows, print a dim explanatory line (e.g. No agents detected.) instead of an empty table.
• Route --json through ui.text like the rest of the CLI.
