Wave 3 rollup: CLI programmatic review path (backs PR #1655)

[cliffhall]

Tracking issue for the Wave 3 rollup PR

Backs #1655 — the CLI programmatic review path rollup, combining the three Wave 3 sub-issues from the #1579 decomposition of PR #1510 into one cumulative PR against v2/main.

• Rollup PR: cli: Wave 3 — programmatic review path (rollup of #1573–#1575) #1655
• Sub-issues (all closed): cli: programmatic ergonomics — --method initialize, --tool-args-json, --connect-timeout, env-var fixes #1573, cli: --app-info probe + --format json envelope #1574, cli: stored-auth suite — --use-stored-auth, --wait-for-auth, --list-stored-auth, --print-handoff #1575

Created so the board tracks the rollup through a real issue card (per AGENTS.md, PRs are not added to the board directly — they are tracked via their linked issue's card).
