Per user direction "可以不放在 vendor 里面，我们移动到自己的工程，
后面就和他们分叉" — promote the two community SDKs from vendor/ to
crates/ so they become first-class OP workspace members we own and
evolve, instead of read-only vendored snapshots.
Moves:
vendor/anthropic-agent-sdk/ → crates/anthropic-agent-sdk/
vendor/copilot-sdk-rust/ → crates/copilot-sdk/
Workspace integration:
- Root `Cargo.toml` exclude list drops both vendor entries; the
existing `members = ["crates/*"]` glob auto-includes them.
- `crates/copilot-sdk/Cargo.toml`: stripped all `[[example]]`
blocks (22 of them) — the examples/ dir was already removed
during the import, and leaving the entries broke
`cargo test --workspace --no-run`.
- `crates/anthropic-agent-sdk/Cargo.toml`: already had its
`[[example]]` blocks pruned in the previous commit.
Lockfile pins (workspace `Cargo.lock`):
Pulling reqwest 0.12.28 (via anthropic-agent-sdk) into the
unified workspace dep graph re-resolved several `icu_*` crates to
the 2.2 line, which requires rustc 1.86. OP's toolchain is 1.85
(locked to stay compatible with the skia-safe-op fork). Pinned:
icu_collections 2.2.0 → 2.1.1
icu_locale_core 2.2.0 → 2.1.1
icu_normalizer 2.2.0 → 2.1.1
icu_normalizer_data 2.2.0 → 2.1.1
icu_properties 2.2.0 → 2.1.2
icu_properties_data 2.2.0 → 2.1.2
icu_provider 2.2.0 → 2.1.1
idna_adapter 1.2.2 → 1.2.1
All eight pins are the latest versions on each crate's 2.1.x /
1.2.x line that compile on rustc 1.85.
Verification:
- `cargo check -p anthropic-agent-sdk` ✓
- `cargo check -p copilot-sdk` ✓
- `cargo test --workspace --no-run` ✓
- `cargo test -p openpencil-shell-core --lib` → 250 pass
- `cargo test -p openpencil-desktop chat_` → 16 pass
Next: replace the hand-rolled subprocess parser in chat_subprocess.rs
with thin per-CLI adapters that route Claude Code through
`anthropic_agent_sdk::SubprocessTransport` and Copilot through
`copilot_sdk::Client + Session`. Gemini stays on the generic stdin
bridge until an upstream Rust SDK exists. Codex + OpenCode get an
HttpServerProvider that spawns `<bin> serve` then connects via a
local HTTP client.
