Installer: multi-repo install, catalog expansion, and a machine-readable catalog export

[marcelolafleur]

Builds on the universal installer (#1142). Three additions:

Install several repos in one run. --repo can be repeated (--repo og-zaf --repo og-idn) or take a comma list; --all installs the whole catalog. (On Windows, where a parameter can't repeat, use the comma form: -Repo og-zaf,og-idn.) Each repo clones into its own subfolder under --dest and installs independently — if one fails it's reported and the rest continue, with a per-repo summary at the end. uv is installed once. A single repo keeps the existing per-step prompts; multiple run as a batch after one confirmation. --branch and --repo-url stay single-repo only.

Expanded catalog. Adds og-zaf, og-idn, og-phl alongside og-core/og-eth, now that they're uv-native.

A reliable way to read the catalog. --list (table) and --list-json (JSON) print the catalog and exit, and scripts/repos.json publishes the same data as a static file — so downstream tooling can stay in sync by fetching one URL instead of scraping the script or --help. A small CI check (.github/workflows/check_catalog.yml) fails if install.sh, install.ps1, and repos.json ever drift apart.

Hands-free, unattended use: bash install.sh --all --dest ~/OG --yes. scripts/QUICK_INSTALL.md is updated for all of the above.

Also tightens a few edges: clean error messages for unknown or missing flag values, and a correct non-zero exit when a non-interactive run can't proceed.

Tested: every selection mode on bash 3.2 (the macOS default) — repeated / comma / --all / dedup / single, plus the guardrail errors — all stopping before any real install; the catalog stays in sync via the new CI check. The PowerShell side mirrors the bash logic and its -ListJson path runs in CI, but I haven't yet run the full multi-repo install loop on Windows.

Nice updates, @SeaCelo. This will make it simple to add additional country calibrations in the future.
