fix(plugin): marketplace source as git-subdir so Claude.ai can resolve the plugin (#1906)

Claude.ai's Add-marketplace backend fetches the manifest and resolves
every plugin source as a repository; the relative ./claude-plugin source
only works where the whole repo is cloned (Claude Code) and surfaced as
'Repository not accessible' on a public repo. git-subdir with the public
repo URL and the plugin path is the documented form for monorepos and the
one the plugin-directory catalog uses.

 [2026-08-25] The production-only _backfill_remaining_20260817 invoice repair snapshot is privilege-contained, not deleted or relocated: PR #1655 identifies it as the safety snapshot for the 337-row 2026-08-17 remaining_amount repair, but the repository establishes neither its retention classification nor approval to destroy financial evidence, so the migration enables RLS, revokes PUBLIC/anon/authenticated access, and limits service_role to read-only for an authorized follow-up review while postgres retains owner control. Neither PR #1655 nor repository history establishes the original repair's behandlingshistorik/rattelse traceability or whether any repaired invoice was linked to a posted voucher; verifying the repair's who/when/what trail and its relation to booked entries is an explicit compliance follow-up, not inferred or altered by this access fix. Default privileges stay unchanged in this scoped fix because Supabase's platform transition and the application's many existing implicit grants require a separate compatibility audit.
 [2026-08-25] Risk ID RISK-2026-08-25-INVOICE-BACKFILL-SNAPSHOT treatment record (PR #1901): Risk Owner and follow-up owner Emil; classification restricted financial remediation evidence pending BFL review; treatment preserves all 337 rows and merges only the anonymous-access containment; BFL retention/rattelse review deadline 2026-09-25; residual risk after containment Low, explicitly including postgres-owner bypass until that review. Retention or deletion requires the separate reviewed follow-up, and this PR must not delete or alter snapshot rows. This entry and PR #1901 are the repository-native Risk Treatment Plan reference because the repository has no risk register.
 [2026-08-25] Plugin distribution goes through the Claude plugin directory (public GitHub link, claude plugin validate, submit from claude.ai admin-settings or Console), not an organisation marketplace: org marketplaces accept private/internal repos only and require the Claude GitHub App, so a public monorepo can never pass that dialog (the 'Repository not accessible' error is misleading). Install-time guidance is a /accounted:setup slash command, the convention Anthropic's own plugins use (commands/*-setup.md); no SETUP.md mechanism exists in the plugin spec.
+[2026-08-25] The marketplace entry for the Accounted plugin is a git-subdir source (public repo URL + path claude-plugin), not the relative path ./claude-plugin: relative sources only resolve when the whole marketplace repo is cloned (Claude Code), while Claude.ai's Add-marketplace backend fetches the manifest and resolves each plugin source as a repository, which surfaced as 'Repository not accessible' on a public repo. git-subdir is also the form the plugin-directory catalog uses for monorepos.
