Prototype Events identity with a localized adapter

[dpeacock]

Why

Make #8426's Events pull/deploy round trip honor module-only object identity while preserving legacy list entries, counts and effective API versions.

Alternative A — localized adapter

An Events-owned adapter handles remote reconstruction and local deploy comparison without expanding generic transform interfaces. Tradeoff: explicit Events dispatch in both callers and pinned per-entry versions.

Shared fixes preserve explicit empty-list clearing and normalize editing identity before fetched strict-schema validation. Outgoing object config has neither root nor nested handles. Needed #8425 robustness fixes are included because the common #8426 base predates them; author branches are untouched.

Review / validation

• Original transform-test structure restored; overlapping integration suites consolidated. Final base diff +936/−73, 31% less churn; cleanup does not change production code or the strict fixture.
• 2,981 app tests passed, 2 skipped; package type-check/lint pass.
• Real fetched-schema/TOML/manifest/no-op regressions retained. Independent cleanup review found no gaps; all four injected regressions failed the retained tests.

Sibling draft alternative to B and C, not intended to merge alongside them. CLI-team approval remains outstanding. Writer gates are unchanged; migration continuity and live Core UUID behavior are unverified. No public changeset while this remains a prototype.

Differences in type declarations

We detected differences in the type declarations generated by Typescript for this branch compared to the baseline ('main' branch). Please, review them to ensure they are backward-compatible. Here are some important things to keep in mind:

• Some seemingly private modules might be re-exported through public modules.
• If the branch is behind main you might see odd diffs, rebase main into this branch.
