fix(sync): release tracking finds version tags without the v prefix

[flipvh]

pnpm cella analyze and pnpm cella sync failed on every new app with no upstream releases (v*) found. Release tracking is the default, it looked for v* tags, and all 60 cella release tags are bare versions (0.18.1, include-v-in-tag: false). raak and projectcampus both set upstreamTrack: 'branch' by hand to get past it.

What changes

• A release tag is a version with or without the v prefix. One pattern in src/utils/git.ts serves the latest release, a pinned --ref and the "published upstream" check, which now passes two globs (tags/[0-9]*, tags/v[0-9]*).
• Component tags (create-cella-0.2.3) and other namespaces (archive/pre-release) still do not count. Git sorts both above every version tag, and both exist in cella.
• The three error messages and the upstreamTrack doc no longer say (v*).

Checked

• Two new e2e cases failed before the fix and pass after it: the latest release with a bare tag next to both decoy tags, and a pinned bare --ref whose commit only the tag publishes.
• pnpm test: 284 passed. pnpm check clean.
• Run from this branch in an app created with pnpm create @cellajs/cella (0.18.1): analyze with default settings resolves 0.18.1 and completes.

After merge

Release 0.3.3, then cella bumps @cellajs/cli with its lockfile. A new app installs from the template's lockfile, so that bump is what delivers the fix.

• Tests: the two bare-tag cases.
• Source: +2 code, +3 comment lines. The pattern gets a name and a comment because three callers share it.
