fix(claude): commit .claude/settings.json to auto-enable reqstool plugins (#69)

* 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. Mirrors reqstool-client's
.gitignore/.claude/settings.json pattern so a fresh clone gets both
plugins auto-enabled.

* fix(claude): track opsx commands and openspec skills

The .gitignore carve-out only kept .claude/settings.json, so the opsx
slash commands (.claude/commands/opsx/*) and OpenSpec skills
(.claude/skills/openspec-*) were never tracked here, unlike
reqstool-client (reqstool/reqstool-client#415). Mirrors that fix so
fresh clones/worktrees of this repo have them too.

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

Generated tool scaffolding (.claude/commands/opsx/, .claude/skills/
openspec-*) is no longer committed (reverted in the prior commit, same
mistake as reqstool-client#415/#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
+(`.claude/commands/opsx/`, `.claude/skills/openspec-*`) — they're CLI-generated tool scaffolding,
+not committed to the repo:
+
+```bash
+openspec update   # or: openspec init --tools claude --force
