* feat(package-manager): implement the `update` command in pacquet Port pnpm's `update` (aliases `up`/`upgrade`) onto pacquet's always-fresh-resolve install path. - Compatible bump: withhold matched names' lockfile pins from the preferred-versions seed (new `UpdateSeedPolicy`) so they re-resolve to highest-in-range; `package.json` is left untouched. This is what distinguishes `update` from `install`. - `--latest`: fetch each matched direct dep's `latest` tag and rewrite the manifest range (`^v`, or exact under `--save-exact`), like `add`. - Selectors: bare-name/glob patterns (`depth>0`, no `--latest`) match every locked package name at any depth; versioned (`foo@2`) or `--latest` selectors match direct deps only; `--latest` + spec is rejected with `ERR_PNPM_LATEST_WITH_SPEC`. - CLI flags: `-L/--latest`, `-E/--save-exact`, `-P/-D/--no-optional` (faithful `makeIncludeDependenciesFromCLI`), `--depth`, `--lockfile-only`, `-i/--interactive` (dialoguer + inline outdated check). - `--global` and `--workspace` error out for now: the global-dir and workspace-version-linking subsystems are not ported yet. The resolver's `UpdateBehavior` tri-state and the npm resolver's `include_latest_tag` already existed; this change drives them from a CLI command.

Negation selectors now work. - Add `--no-save`: the range rewrites still drive resolution (lockfile updates) but `package.json` is not persisted. Mirrors pnpm's `updatePackageManifest: opts.save !== false`. - Add `ERR_PNPM_NO_PACKAGE_IN_DEPENDENCIES`: a selector that matches no direct dependency under `--depth 0` (without `--latest`) now errors, matching pnpm; `--latest` with an unmatched selector is a no-op. Ports the negation-pattern, `--no-save`, and no-package-in-deps tests from pnpm's `installing/commands/test/update/update.ts`.

Parse the (small) update-target set to `PkgName` once and compare against `key.name` directly. Addresses a review comment on #12102. Written by an agent (Claude Code, claude-opus-4-8).
