chore(http-action): mark 0.1.0 as beta for release

[rmyndharis]

Summary

Promotes http-action 0.1.0 from development to beta ahead of its first tagged release.

Changes

• Status flip: manifest.json development\ → beta. Regenerates plugins.jsonand the root +http-actionREADME detail blocks vianpm run catalog`.
• Secret sentinel test: adds a regression guard asserting the configured auth token is placed in the outbound request header (so the auth path is actually exercised) yet never appears in logs or the sent reply. The token is kept out of the template context by design; this test pins that invariant so a future change that interpolates headers or URL into a log line will fail it.

Verification

• node --import tsx --test "http-action/*.test.ts" → 110 pass / 0 fail
• npm run typecheck → clean
• npm run catalog:check → up to date (10 plugins)
• node package.mjs http-action → http-action.zip 7.1 KB

Followed by tag http-action-v0.1.0 after merge to cut the GitHub Release.
