v4.2.0 — First-time-user UX fixes

Three frictions reported on the v4.1 scaffolding flow are fixed.

Change	Why
`ctx init` is now recursive (4 levels deep, `--depth N` or `--no-recursive` to opt out)	v4.1 only scanned the root, so monorepos with `frontend/` + `api/` saw only the root manifest. Vendored dirs are skipped (`node_modules`, `.venv`, `vendor`, `dist`, `build`, `target`, ...). Each rationale line is prefixed with the relative path.
`ctx eval-init <name> [--target rag\|anthropic_skill]`	First-time users hit "Invalid value for SUITE_FILE" because the suite is a hand-written artefact. `ctx eval-init` scaffolds one with a realistic case so `ctx eval ... --dry-run` works immediately.
Friendlier `ctx eval` error	Missing suite file → actionable hint pointing at `ctx eval-init`, not Typer's generic "File does not exist".
README rewrite (EN + FR)	New Input / Output columns on the CLI table + 11 numbered worked examples covering `create → init → compile → lint → audit → eval-init → eval → upgrade`. Every command's `--help` now includes an `Examples:` block.

1178 passed, 1 skipped (Anthropic key absent)
mypy --strict clean across 178 files
ruff check + ruff format clean
11 new tests: recursive walk (depth cap, skip list, symlinks), ctx eval-init for both targets, friendly eval error
