chore: sync release-please manifest + version files to 0.8.1

[koko1123]

Follow-up to #105.

Why

v0.8.1 was hand-tagged out-of-band at 0b5a320 (#104, the KMS fix) so perpcity-zig-sdk could bump -- and that happened after #105 had already synced main to 0.8.0. So main's manifest is one version behind the latest tag: the exact drift #105 fixed, shifted up a notch.

ref	manifest	build.zig.zon
v0.8.1 tag (#104)	0.7.0	0.7.0
main (pre-this-PR)	0.8.0	0.8.0
main (this PR)	0.8.1	0.8.1

What

Bump the manifest + the three release-please extra-files (build.zig.zon, README.md, docs/content/docs/installation.mdx) 0.8.0 -> 0.8.1 to match the existing v0.8.1 tag.

Effect on release-please

Now that the org "Allow GitHub Actions to create and approve PRs" setting is enabled, merging this lets release-please:

• treat 0.8.1 as already released (the v0.8.1 tag exists at 0b5a320),
• retire its stranded release-please--branches--main branch, and
• cleanly propose 0.8.2 for the next real feat:/fix: change.

It does not re-tag or move v0.8.1 -- that tag is load-bearing (pinned by perpcity-zig-sdk and gator-liquidators at its exact SHA).

Not in scope (follow-up)

Backfilling the missing v0.8.0 + v0.8.1 GitHub Releases (git tags exist, but no GitHub Release for either).

Verification

• ZIG=$HOME/.zig-0.16.0/zig make ci (build + fmt --check + test) -- green.
• No stray 0.8.0 refs remain in the four tracked files.
