Claude 765c1dfd7e feat: generate translator credits offline from the committed file
Makes docs/changelog/translators.json self-sufficient so a release no longer
needs to re-query Crowdin:

- sinceLastTag entries now carry each translator's languages ({user, languages}),
  recorded by the --seed run.
- Default mode (no flags) is offline: it generates the "## Translations" block
  straight from the committed file — reading sinceLastTag, grouping by the stored
  languages, and resolving npubs via the mappings registry. No token, no network.
- --seed/--raw remain the online paths (CI seeding / debugging). curl + git +
  credentials are only required there; the offline path needs just jq.

RELEASE_OPS now points at the tokenless `scripts/translators.sh` for the
changelog credits.

# Build the changelog "## Translations" section, or keep its data file seeded.
#
# Default (no flags): OFFLINE. Generate the ready-to-paste credit block straight
# from docs/changelog/translators.json — no token, no network. This is the
# release-time command: it reads the sinceLastTag snapshot (kept fresh by CI,
# with each translator's languages) and resolves npubs via the mappings registry,
# grouping by language. Anyone without an npub is listed under UNMAPPED.
#
# scripts/translators.sh # print the block for the current cycle
#
# --seed: ONLINE. Query Crowdin's "Top Members" report for the window and update
# translators.json (see the two lists below). Used by CI; needs a token.
#
# scripts/translators.sh --seed
#
# Flags:
# --seed Refresh translators.json from Crowdin (online). Window is
# --from..--to.
# --raw Dump the raw per-member report rows to stderr (online; for
# discovering Crowdin usernames). Implies an API call.
# --from / --to Window for --seed/--raw. A date (YYYY-MM-DD) or a git tag/ref
# (resolved to its commit date). --from defaults to the most
# recent v* tag ("since the last release"); --to defaults to now.
# --mapping PATH Override the data file (default docs/changelog/translators.json).
#
# Environment (only needed for --seed/--raw; same names crowdin.yml uses):
# CROWDIN_PROJECT_ID Crowdin numeric project id.
# CROWDIN_PERSONAL_TOKEN Crowdin personal access token (needs report scope).
#
# docs/changelog/translators.json (kept alongside the changelogs) holds two lists:
# mappings A forever-growing Crowdin-username/id -> npub registry. --seed
# appends new contributors with a blank npub and never deletes or
# overwrites existing entries.
# sinceLastTag A rolling snapshot of who has translated since the last release
# tag — each entry is { user, languages } — refreshed on every
# --seed run. The offline credit block is generated from this.
#
# Requires: bash, jq (always); curl, git (only for --seed/--raw).
#
# NOTE: --seed/--raw talk to the live Crowdin REST API (api.crowdin.com). The JSON
# field paths for the "top-members" report are documented at
# https://developer.crowdin.com/api/v2/#operation/api.projects.reports.post and
# can be adjusted in the jq blocks below if Crowdin changes the schema.
