Tom Boucher d77170a25d perf(#312): index argv once in parseNamedArgs (#392)
parseNamedArgs re-scanned argv with indexOf/includes once per flag —
O(flags * argv) — on the command-dispatch hot path (24 call sites across
gsd-tools + init/state/validate routers). Build a first-index Map of argv
tokens in a single pass and use it for the flag lookups, dropping it to
O(argv + flags). Semantics are identical: firstIndex.get(t)??-1 === indexOf(t),
firstIndex.has(t) === includes(t); first-occurrence-wins and the value-token
rejection are preserved. Adds the first behavior-lock tests for the module.

Changeset Fragments

This directory holds per-PR CHANGELOG fragments. Every PR with user-facing changes drops one (or more) <random-name>.md files here describing its CHANGELOG entry. Fragments are consolidated into the top-level CHANGELOG.md at release time.

Why

Two PRs that both edit the ### Fixed block of CHANGELOG.md always conflict on merge — git can't pick a serialization order without human input. Two PRs that each add a fresh .changeset/<unique-name>.md never conflict because they don't share lines.

See #2975 for the full rationale.

Adding a fragment

node scripts/changeset/new.cjs \
  --type Fixed \
  --pr 1234 \
  --body "fix the thing — explain the user-visible change in one sentence"

This writes .changeset/<adjective>-<noun>-<noun>.md with frontmatter and a body. Three random words → concurrent PRs don't collide.

Format

---
type: Fixed
pr: 1234
---
**`/gsd-foo` no longer drops trailing slashes** — explain the user-visible change.

Allowed type: values follow Keep a Changelog: Added, Changed, Deprecated, Removed, Fixed, Security.

Opting out

PRs that legitimately have no user-facing impact can add the no-changelog label. CI honors it. When unsure, add the fragment.

At release time

node scripts/changeset/cli.cjs render --version vX.Y.Z --date YYYY-MM-DD

Reads every fragment, groups bullets by type:, replaces ## [Unreleased] with a new ## [vX.Y.Z] - YYYY-MM-DD block, opens a fresh ## [Unreleased] above, deletes consumed fragments. Idempotent.
