chore(release): bump version to 0.7.8

[shujaatTracebloc]

Release bump so a v0.7.8 tag can be cut to build the next ingestor image.

Why

develop/master are one commit ahead of the v0.7.7 release image: the validator log-label normalization fix (#397). No image contains it yet because the image is built only by release-image.yml on a v*.*.* tag push.

What

• tracebloc_ingestor/__init__.py: 0.7.7 → 0.7.8

After merge

Tag v0.7.8 on develop → release-image.yml builds & pushes ghcr.io/tracebloc/ingestor:0.7.8 (+ :0.7, :0), signs it, and writes the digest to the GitHub release. Prod stays on 0.7.7 until images.ingestor.prodDigest in the client chart is updated to the new digest.

Note

Low Risk
Single-line version string change with no behavioral impact; production stays on 0.7.7 until the chart digest is updated.

Overview
Release version bump from 0.7.7 to 0.7.8 in tracebloc_ingestor/__init__.py (__version__), the package’s single source of truth that setup.py reads at build time.

No runtime or ingestor logic changes in this PR—it only prepares cutting a v0.7.8 tag so release-image.yml can build and publish the next ingestor image (including the validator log-label fix from #397 that isn’t in the 0.7.7 image yet).
