* feat(uvx): add uvx (uv tool run) package executor

Adds support for `uvx`, implemented as a PyPI Executor alongside pipx.
uvx is an alias for `uv tool run`: it installs a tool into an ephemeral
environment and runs it, so it has no install/list subcommand and the
first positional argument (or --from) is the package to audit.

Parsing highlights:
- --from overrides the positional command as the package to audit
- --with packages are audited as additional environment dependencies
- name@version shorthand (ruff@0.3.0, ruff@latest) is normalized
- flag parsing stops at the tool name so the tool's own flags are not
  misread as uvx options; uvx's value/boolean flags are registered so
  none greedily consume the package positional
- VCS/URL/local-path specs are skipped for registry auditing

Wires up command registration, analytics, shell alias/shim, cloud audit
mapping, a dedicated `uvx` sandbox profile (UV_*/PIP_* env, uv cache and
tool dirs), config policy, docs, unit tests and an E2E workflow step.

Closes #326

* chore(uvx): align docs and base profile with uvx support

Incorporates the low-risk, non-parser improvements from the community
PR #345 (author non-responsive) into our implementation:

- list uvx (and the previously-missing pipx) as PyPI managers in the
  pypi-restrictive base profile package_managers and its README, so the
  base profile applies directly when selected via --sandbox-profile
- document uvx in docs/github-action.md and docs/proxy-mode.md
- add version / IsExplicitVersion assertions to the uvx parser tests

Our pflag-based parser is kept as-is: unlike #345 it audits --with
packages and handles all uvx short flags (e.g. -w), both of which the
community PR misses.

* fix(uvx): skip interpreter requests; use require in tests

Addresses review feedback on PR #357:

- uvx interpreter requests (`uvx python`, `uvx python@3.12`, `uvx pypy`,
  ...) launch an isolated interpreter rather than installing a PyPI tool.
  Treating the positional as a package made the guard flow resolve/analyze
  pkg:pypi/python (and python==3.12), which could wrongly block or fail a
  valid invocation. Skip these for the positional; --with packages on the
  same command are still audited.
- Use require.NoError / require.Len for fatal assertions in the uvx tests,
  matching the repo's testing convention, so a failure stops the subtest
  before a nil dereference instead of panicking.

* docs(uvx): document fail-open and --with-requirements trade-offs

Record the two deliberate parsing decisions raised in review as in-code
trade-off comments (no behavior change):

- unknown flags are tolerated (fail open), consistent with the other
  executors; the residual gap only affects non-proxy guard mode since the
  default proxy flow intercepts every registry download.
- --with-requirements / --with-editable values are consumed but not
  expanded into audit targets; expanding them needs manifest-extractor and
  guard changes, tracked as follow-up. Proxy mode still covers them.

* docs(uvx): drop --with-requirements limitation note

Per maintainer review: guard mode is being deprecated and auditing the
contents of an existing requirements file is a scanner's responsibility,
not PMG's. Remove the "known limitation / follow-up" note; the flags stay
registered only so their values are not mistaken for the tool positional.

46cc70db53 feat: add GitHub Action for one-step PMG setup in CI (#263)
* feat: add GitHub Action for one-step PMG setup in CI

Composite action at repo root that downloads PMG (with SHA-256 verification
against the upstream checksums.txt), runs `pmg setup install`, and wires
shims onto $GITHUB_PATH so subsequent `npm install` / `pip install` calls
are transparently analyzed.

Defaults are conservative: malware blocking + dependency cooldown + proxy
mode (matching PMG's own defaults). Sandbox is opt-in because enabling
Landlock/Bubblewrap on ubuntu-latest requires relaxing AppArmor
user-namespace restrictions.

Cloud sync uses the documented SAFEDEP_API_KEY / SAFEDEP_TENANT_ID env-var
fallback so we skip the keychain codepath that has no usable backend in
headless CI. When cloud is enabled and no endpoint-id is supplied, the
action sets PMG_CLOUD_ENDPOINT_ID=github-actions/${GITHUB_REPOSITORY} so
events aggregate per repository instead of per ephemeral runner hostname.

Closes #248.

* fix(action): drop github.repository template from input description

Action manifest validation rejected the action.yml because the endpoint-id
input description contained ${{ github.repository }} — template expressions
aren't evaluated in input description text and trip the validator with
"Unrecognized named-value: 'github'". This caused every job using uses: ./
to fail before any step ran.

Also switch the config-file e2e job to verify the staged file directly
instead of calling `pmg config get`, which is not in the v0.13.0 release
that "latest" resolves to today.

* fix(action): address review comments on PR #263

- Drop opinionated defaults on PMG_* toggle inputs. All defaults are now
  empty strings, and the action only exports PMG_* env vars when the
  caller explicitly sets the input. Without this, defaults like
  PMG_PARANOID=false silently shadowed config-file overrides because env
  vars beat config.yml in Viper precedence.
- Verify cached PMG against upstream checksums.txt on every cache hit.
  The cached tarball is stored alongside the binary and re-hashed against
  the freshly-fetched checksums.txt; on drift, the cache entry is evicted
  and re-downloaded.
- Export PMG_* env vars BEFORE running `pmg setup install` so settings
  like disable-telemetry actually apply during setup, not just to
  subsequent package-manager calls.
- Add `|| true` to the grep that extracts the expected checksum so
  set -e doesn't kill the script before the friendly error message fires
  when no checksum entry is found.
- Pin third-party actions (actions/checkout, actions/setup-node) to
  commit SHAs to match the repo's supply-chain hardening convention.
- Fix the malicious-package E2E test capturing tee's exit code instead
  of npm's; redirect to a file and check the actual command exit code.
- Add an E2E job that asserts PMG_PARANOID is unset when only
  config-file is provided — regression guard for the precedence fix.

* ci(action-e2e): scope sandbox tests to action setup, not PMG runtime

The landlock job was running `npm install express` with no explicit
sandbox profile and the default profile blocks something npm needs
(PMG's own e2e uses `--sandbox-profile npm-restrictive` to make this
viable). Bubblewrap happened to pass, but verifying the default sandbox
profile is permissive enough for arbitrary package installs is PMG's
e2e responsibility — this workflow's job is to assert the action wires
sandbox config correctly.

Switch both drivers to a matrix and verify only what the action owns:
PMG_SANDBOX_* env vars propagated, pmg binary runs, bwrap is installed
when requested, AppArmor user-ns restriction relaxed.

* ci(action-e2e): bump setup-node to 24

Node 20 reached end-of-life and setup-node now warns on it. Match the
version pinned by publish-npm.yml (the repo's newest workflow). Updated
the README and docs/github-action.md quick-start examples to match.
