fix(plugins): do not claim a host application the portable bundle cannot know

Review point. The portable bundle is built with host "coding-agent", and the
build wrote that straight into PLATFORM_APPLICATION, so every portable install
sent X-Application: coding-agent.

That value is not in the platform's allowlist, so it was already being dropped
server-side. The effect was the worst of both: the wire claimed we knew the
editor, the stored event recorded that we did not, and nothing said which was
right. An absent header says the same thing honestly and costs a lookup.

HARNESS_ID stays "coding-agent". It is the PostHog-side label, it is true, and
grouping portable installs together there is useful.

Native bundles are unchanged apart from the regenerated comment. Covered by two
new build tests: portable declares no application, and each native names the
host it was generated for.

into `OTHERS`. A new value has to land in the platform's `EventSource` enum, so
do not invent one without that change going in too.
`X-Application` is allowlisted the same way, and this one has a rule of its own:
**omit the header when you do not know the host.** A value outside the allowlist
is discarded server-side, so guessing produces an event that claims an
attribution we do not actually have. The portable bundle is the case that
matters. It runs in whatever editor a user drops it into, so its build leaves
`PLATFORM_APPLICATION` empty and `memory_core` sends no header at all, while the
native bundles each name the host they were generated for. If you add a build
target, decide which of those two it is.
## Adding an integration
1. For a native coding-agent host, add `integrations/<name>-plugin/` with `plugin-build.json`, its manifest, and a thin adapter, then generate its shared runtime. Portable clients use the single `mem0-agent-plugin/` package. Independent TypeScript integrations stay self-contained and import shared lifecycle behavior from `agent-plugin-core/typescript/`.
