fix(claude): commit .claude/settings.json to auto-enable reqstool plugins (#132)

* fix(claude): commit .claude/settings.json to auto-enable reqstool plugins

The reqstool@reqstool-ai and reqstool-openspec@reqstool-ai plugins were
never installed for this repo's checkout path, since .claude/ was
blanket-gitignored and the marketplace/enabledPlugins config that
reqstool-client commits was never added here (a local .claude/settings.json
existed but was missing the extraKnownMarketplaces entry). Mirrors
reqstool-client's .gitignore/.claude/settings.json pattern so a fresh
clone gets both plugins auto-enabled.

* docs(contributing): note openspec update for opsx commands/skills

Generated tool scaffolding (.claude/commands/opsx/, .claude/skills/
openspec-*) is intentionally not committed (same convention as
reqstool-client#416) -- contributors using Claude Code need to
regenerate it locally after cloning.

* docs(contributing): document reqstool/openspec CLI prerequisites

Neither CLI was documented as a prerequisite anywhere. Also notes the
Claude Code marketplace/plugin prompt contributors will see on first
open, now that .claude/settings.json enables it by default.

+If using Claude Code, opening this repo will prompt you to confirm adding the `reqstool-ai`
+marketplace and enabling the `reqstool`/`reqstool-openspec` plugins (configured in
+`.claude/settings.json`) — accept the prompt.

+Then regenerate the `opsx` slash commands and OpenSpec skills
