feat(telemetry): switch to SendForModule for auto-version resolution

Replace telemetry.Send(name, PKG_VERSION) with telemetry.SendForModule
so the binary reports its release version automatically from
runtime/debug.BuildInfo whenever PKG_VERSION isn't injected (e.g.
`go install` without ldflags). The goreleaser path still wins because
goreleaser's -X main.PKG_VERSION={{.Version}} populates the fallback,
but `go install github.com/lukaszraczylo/semver-generator@vX.Y.Z`
users now also get the correct version without ldflag plumbing.

Bumps oss-telemetry to v0.2.1.

 ### How does it work
 
@@ -29,10 +35,12 @@ Project created overnight, to prove that management of semantic versioning is NO
 
 * With flag `-e` or config `force.existing: true` the existing tags in versioning will be respected, helping you to avoid the version conflicts.
 * With config `force.commit: deadbeef` where `deadbeef` is the commit hash - calculations will start from the specified commit.
+* Tag prefix stripping: The `v` prefix is automatically stripped from tags (e.g., `v1.2.3` → `1.2.3`). Additional prefixes can be configured via `tag_prefixes` for monorepo setups (e.g., `app-1.2.3`, `infra-1.2.3`).
 
 ### Important changes
 
 * From version `1.4.2+` as pointed out in [issue #12](https://github.com/lukaszraczylo/semver-generator/issues/12) commits from merge will not be included in the calculations and commits themselves will bump the version on first match ( starting checks from `patch` upwards ).
+* Added support for blacklisting terms to ignore specific commits, branch names, and merge messages from version calculations.

+#### Tag prefix stripping
+
+When using the `-e` (existing tags) flag, the semver-generator needs to parse existing git tags to determine the current version. Tags often include prefixes that need to be stripped before version parsing.
+
+**Automatic `v` prefix stripping:**
+The `v` prefix is always stripped automatically from tags. For example:
+- `v1.2.3` → parsed as `1.2.3`
+- `v0.5.0` → parsed as `0.5.0`
+
+**Custom prefixes for monorepos:**
+In monorepo setups where different components have their own versioned tags, you can configure additional prefixes to strip:
+
+```yaml
+tag_prefixes:
+  - "app-"
+  - "infra-"
+  - "api-"
+  - "frontend-"
+```
+
+With this configuration:
+- `app-1.2.3` → parsed as `1.2.3`
+- `infra-0.5.0` → parsed as `0.5.0`
+- `api-2.0.0-rc.1` → parsed as `2.0.0-rc.1` (release candidate)
+
+This is particularly useful when:
+- You have multiple services/components in a single repository
+- Your CI/CD creates tags with component prefixes
+- You want to track versions separately for different parts of your codebase
