chore(crates): move vendored SDKs into workspace as forkable crates

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.
