## Summary
Adds the semantic-convention evolution foundation:
- vendors the OpenTelemetry schema and SigNoz overlay
- generates Go and TypeScript family tables deterministically
- exposes the Go resolver API for family members, current names, and
historical names
- adds generation checks and unit tests
Related to #6143.

## Testing
- `go test ./scripts/semconv`
- `go test ./pkg/types/telemetrytypes/semconv`
- `make semconv-check`
## Risk and rollback
This layer is additive apart from CI generation checks. Roll back by
reverting this PR; no stored telemetry is changed.
Freezes an absolute-truth oracle from prometheus@v0.311.3's own
promql/promqltest testdata: a generator command (scripts/promqltestcorpus, go run .)
evaluates upstream's load scripts with the vendored reference engine and
writes 755 cases to a committed corpus; a new integration suite replays
the ingestion and asserts /api/v5/query_range responses against it. The
known-divergences ledger is enforced exactly in both directions and is
empty: the serving path matches the reference engine on every case.
Also folds in the last serving-path fix the corpus surfaced: the v5
output filter dropped every __-prefixed label, mangling labelsets that
legitimately carry one (e.g. __address__); it now strips only known
storage keys (__temporality__, __scope./__resource. prefixes).
The metrics fixture writes registration rows per (series, hour bucket)
with hour-floored timestamps, matching the exporter; the queriermetrics
dormant-metric warning test now uses genuinely dormant data (production-
shaped registration shares an hour bucket with recently-stale data).

This is the second part of the OSS installation and improvement PR.
Users must run the migration script to migrate an existing SigNoz installation from Docker Standalone or Docker Swarm.
