Prepare the plugin for community-marketplace submission (JPA-4586)

[paltsevpaveljoom]

Summary

Review of this repo against the current Claude plugin submission requirements
(internal ticket JPA-4586). It was not ready — two blockers, both fixed here.

Worth recording: there is no application process for the official
marketplace (claude-plugins-official); Anthropic curates it at its discretion.
Third-party submissions go to the community marketplace
(claude-plugins-community) via an in-app form. This PR prepares the repo for
that submission.

Blocker 1 — stale repo name

The repo was renamed pulse-skills → joompulse-skills, but the manifests and
README were never updated. Both homepage/repository URLs and the install
commands still pointed at joomcode/pulse-skills, which resolved only through
GitHub's rename redirect.

The plugin is renamed to joompulse-skills to match the repo and the brand, and
all six stale references are fixed. A plugin name is a permanent identifier
once published — renaming after approval breaks every existing install — so
this is the last point at which the rename costs nothing. Skills now invoke as
/joompulse-skills:<skill>.

Blocker 2 — version drift

plugin.json said 0.1.0 while the changelog carried three skills under
"Unreleased" and thirteen more that were never recorded at all. There were no
tags or releases. Disagreement between manifest, changelog and tags is the most
common cause of submission rejection. This cuts 0.2.0 and rebuilds the entry
from the actual git history.

After merge this should be tagged v0.2.0 to keep the versioning contract intact.

Also included

• Bundled .mcp.json so installing the plugin configures the JoomPulse
  connector and the user only has to sign in. All 17 skills hard-require it, and
  review weighs how fast an unfamiliar user can get a plugin working. The README
  keeps the manual steps for Claude chat and Cowork, where it is still added by hand.
• scripts/check-manifests.sh + CI workflow covering exactly what broke here:
  name/version/URL agreement across both manifests and the changelog, plus skill
  frontmatter and the 1024-character description limit. claude plugin validate
  runs unauthenticated, so it works in CI.
• gitignored skills.zip, a build artifact that was sitting untracked.

Verification

claude plugin validate . --strict, check-public-safety.sh and
check-manifests.sh all pass. Already fine before this PR: directory layout
matches spec, all 17 skills have valid name+description frontmatter (longest
1017 chars), and MIT/SECURITY.md/CONTRIBUTING.md are present.

Notes for the reviewer

• The 0.2.0 date is set to 2026-08-13. If the release lands later, move it.
• The name change is the one irreversible decision here; worth a deliberate look
  before merge.

Public-Safety Checklist

• No credentials, tokens, keys, or secrets.
• No internal filesystem paths.
• No private Slack, Jira, Notion, admin, or service URLs.
• No private service names or implementation details.
• No customer data or private product data.
• Skill directory name matches SKILL.md frontmatter name.
