[rosary-1b914d] feat(schema-bridge): lift from cloister (Apache-2.0)

[jamestexas]

Summary

Lifts cloister/tools/schema-bridge/ into notme/packages/schema-bridge/. capnp → zod TypeScript codegen now lives next to the notme/schema/*.capnp it consumes.

• Re-licensed AGPL-3.0 → Apache-2.0 by sole author (no third-party contributions in the cloister copy, verified via git log).
• Headers injected on every .rs file: SPDX, copyright, one-line provenance pointing at packages/schema-bridge/NOTICE.
• Wires task gen:zod (regenerate) and task gen:zod:check-drift (CI gate) into Taskfile.yml. Build target: task schema-bridge:build.
• Not added to pnpm-workspace.yaml — schema-bridge is a Rust crate. Discoverable via the Taskfile entries.

Cross-links:

• Bead: rosary-1b914d (this lift)
• Epic: rosary-185bca
• Follow-on: rosary-8d2c78 — schema-bridge needs to tolerate /go.capnp's annotation declarations so task gen:zod actually emits for identity.capnp (it currently fails fast with a clear unmapped annotation diagnostic — by design until that bead lands).

Falsification

Every lifted .rs file's content, with the injected SPDX/Copyright/Origin lines stripped, hashes byte-for-byte to the cloister baseline:

FILE                       CLOISTER  ==  NOTME
src/error.rs               b8fad0…f068fa  OK
src/inputs/capnp.rs        0ee7b9…85e540  OK
src/inputs/mod.rs          1fdcb2…e0fda5  OK
src/ir/mod.rs              643059…f58b39  OK
src/lib.rs                 559895…2bfe58  OK
src/main.rs                53845f…823ff5  OK
src/outputs/mod.rs         054fba…fc7bd   OK
src/outputs/zod.rs         d69b94…92dc5c  OK
tests/integration.rs       62f1e6…e76e52d OK

(Full hashes in commit message / falsification script run.)

Tests match cloister baseline: 13 passed, 3 ignored, 0 failed.

Test plan

• cargo build from packages/schema-bridge/ succeeds
• cargo test passes (13/13 active, 3 known-ignored — identical to cloister)
• Falsification passes for every lifted .rs file
• task schema-bridge:build succeeds at repo root
• task gen:zod runs (fails on identity.capnp with a clear diagnostic about the /go.capnp annotation declarations — documented inline; tracked as rosary-8d2c78)
• Cloister-side deprecation of tools/schema-bridge/ — separate bead, not in scope here

Pull request overview

This PR lifts the schema-bridge Rust crate into packages/schema-bridge/ and wires up repo-level Taskfile targets to build a Cap’n Proto compiler plugin that emits Zod + TypeScript types from .capnp schemas, with a fail-fast “unmapped construct” policy.

Changes:

• Added packages/schema-bridge/ Rust crate (parser IR + Zod emitter + capnp plugin binary) and integration tests.
• Added Taskfile tasks to build the plugin and attempt Zod regeneration / drift checking.
• Added crate documentation and licensing/provenance notices for the lift + relicense.
