3ae2c30f2f feat(skills): import skills from projects (#9620)
## Thinking Path

> - Paperclip is the open source control plane people use to manage
AI-agent companies.
> - Company skills make reusable agent behavior discoverable and
editable from one place.
> - Projects already contain skill directories, but operators had to
import each skill path manually.
> - Copying those skills would break the desired write-through workflow
between Skill Studio and the source project.
> - The server therefore needs a safe preview/select/import contract
that only accepts rediscovered, workspace-contained candidates.
> - The UI needs a guided project picker that explains reference
semantics, handles conflicts, and remains usable on mobile.
> - This pull request adds that end-to-end project skill import flow
with authorization, tenant-scope, traversal, and symlink regression
coverage.
> - The benefit is faster bulk onboarding while keeping project files as
the single source of truth.

## Linked Issues or Issue Description

**Feature request**

**Problem:** Importing several skills already stored in a Paperclip
project requires operators to discover and submit each local path
individually. This is slow, hides which well-known directories were
searched, and makes conflict/already-imported states difficult to
evaluate before mutation.

**Proposed solution:** Add an “Import skills from project” flow that
previews skills from well-known directories, lets operators selectively
import eligible candidates, and stores local-path references so Skill
Studio edits write through to the project files.

**Alternatives considered:** Copying files into company-managed skill
storage was rejected because it creates divergent copies. Trusting
client-supplied paths was rejected because imports must be constrained
to server-rediscovered, workspace-contained candidates.

**Additional context:** GitHub duplicate search found no existing issue
or PR for this exact workflow. Refs #3799 for related skill-import
inventory behavior; this PR does not claim to close that issue.

## What Changed

- Extend `scan-projects` with backward-compatible preview and
selective-import modes, typed validation, candidate statuses, and
OpenAPI coverage.
- Discover project skills under `skills`, `.agents/skills`,
`.claude/skills`, `.codex/skills`, `.cursor/skills`, `.opencode/skills`,
and `.gemini/skills`.
- Re-discover selections server-side, enforce company/project/workspace
scope, and reject traversal or symlink escapes before creating
`local_path` references.
- Add the Skills-page menu entry and responsive project import dialog
with project selection, grouped candidates, select all/deselect all,
conflicts, empty/error/403 states, and import results.
- Add route, service, and component regressions for preview
authorization, cross-tenant selections, traversal/symlink safety,
selection counts, grouping, and result semantics.

## Verification

- `pnpm exec vitest run
server/src/__tests__/company-skills-service.test.ts
server/src/__tests__/company-skills-routes.test.ts
ui/src/pages/skills/ImportSkillsFromProjectDialog.test.tsx` — 3 files,
81 tests passed.
- `pnpm check:token-gates` — all token gates clean.
- `pnpm --filter @paperclipai/shared typecheck` — passed.
- `pnpm --filter @paperclipai/server typecheck` — passed.
- `pnpm --filter @paperclipai/ui typecheck` — passed.
- Security review passed after adding tenant-scope and
unauthorized-preview regressions; UX re-review approved desktop/mobile
surfaces; QA passed all seven acceptance areas including write-through
editing, deduplication, conflicts, empty state, and permission denial.

## Risks

- Files remain referenced in project workspaces, so moving or deleting a
source directory can make an imported skill unavailable; the UI
explicitly communicates the reference behavior.
- New well-known directory scans may discover more candidates than older
versions, but preview mode prevents mutation until the operator confirms
a selection.
- The endpoint remains backward compatible: omitting `mode` preserves
the prior full-import behavior.
- No schema migration or telemetry event changes.

> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. Feature PRs that overlap
with planned core work may need to be redirected — check the roadmap
first. See `CONTRIBUTING.md`.

## Model Used

- Anthropic Claude Opus 4.8 with tool use/code execution assisted with
the UI implementation and UX polish. OpenAI Codex CLI with tool use/code
execution assisted with server implementation, security fixes,
regression coverage, integration, and PR preparation; the runtime did
not expose Codex's exact backing model ID or context-window size.
