feat(skills): let agents update company skills safely (#15049)

## Thinking Path

> - Paperclip is an open source control plane for AI-agent companies.
> - Company skills give agents reusable work instructions.
> - Skill Studio can edit skill files and save version history.
> - Agents can create a skill, but they do not have a first-class update
tool.
> - An agent update needs a version check and safe retry behavior to
prevent lost edits.
> - This pull request adds `update_skill` through the existing company
skill file API.
> - The change keeps company policy, version history, and audit records
in one path.

## Linked Issues or Issue Description

**Subsystem affected**

Cross-cutting: the server API, shared validation, and runner tool
catalog.

**Problem or motivation**

An agent can create a company skill but cannot update its `SKILL.md`
through a first-class tool. An unguarded retry can also create duplicate
versions or overwrite a newer edit.

**Proposed solution**

Add `update_skill` with a required current version ID and a retry key.
Route it through the existing skill file API. Reject stale versions and
changed-input retries. Save the version and audit event together.

**Alternatives considered**

A separate write endpoint would duplicate the Skill Studio mutation path
and policy checks. This PR reuses that path instead.

**Roadmap alignment**

This work extends Skills Manager and Skill Studio, which are listed in
`ROADMAP.md`.

**Additional context**

The tool accepts a complete `SKILL.md`, not a partial patch. Callers
must read the current version before they edit it.

## What Changed

- Add optional version and retry fields to the existing skill file
update contract.
- Add a guarded API update with a stable retry receipt and attributed
audit event.
- Add `update_skill` to native and semantic runner tool catalogs, with
mode and policy gates.
- Add unit, integration, protocol, and semantic-tool regression
coverage.
- Document agent use and extend the OpenAPI request contract.

## Verification

- Focused tests and direct server and runner TypeScript checks passed
before this PR.
- `git diff --check` passed after the rebase onto `master`.
- CI passed on the latest PR head, including the full test matrix,
typecheck, and build. Local full typecheck and build stopped because
`cargo` is not installed. The local full test run ended without a
verdict.
- No dedicated end-to-end eval scenario was added or run. The protocol
coverage and semantic-tool test cover the new action deterministically.
- Reviewers can read a skill version, call `update_skill`, repeat the
same key, then try a stale version and a changed-input key. Only the
first edit must create a new version.

## Risks

- File writes and database transactions must stay in sync when a write
fails. The integration tests cover failed writes and retry behavior, but
CI must verify them on the PR head.
- Existing Skill Studio callers do not send the new optional
coordination fields. Their request shape remains valid.

## Model Used

- OpenAI Codex CLI assisted with this change. The runner did not expose
the exact model ID or context window. The agent used code execution and
repository tools.

## Checklist

- [x] I have included a thinking path that traces from project context
to this change
- [x] I have specified the model used (with version and capability
details; exact model ID and context window were not exposed)
- [x] I have checked ROADMAP.md and confirmed this PR does not duplicate
planned core work
- [x] I have searched GitHub for duplicate or related PRs and linked
them above
- [x] I have either (a) linked existing issues with `Fixes: #` / `Closes
#` / `Refs #` OR (b) described the issue in-PR following the relevant
issue template
- [x] I have not referenced internal/instance-local Paperclip issues or
links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip`
URLs)
- [x] My branch name describes the change (e.g. `docs/...`, `fix/...`)
and contains no internal Paperclip ticket id or instance-derived details
- [x] I have run tests locally and they pass (focused tests; full suite
is pending CI)
- [x] I have added or updated tests where applicable
- [x] I have updated relevant documentation to reflect my changes
- [x] I have considered and documented any risks above
- [x] All Paperclip CI gates are green (53 pass, 4 skip on the latest
head)
- [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups
- [x] I will address all Greptile and reviewer comments before
requesting merge
