[dist] add agent and package channels

[bvolpato]

Summary

• Add installable Codex and Claude packages containing MCP configuration plus focused ivygrep context skill.
• Build cross-platform MCPB bundles, publish MCP Registry metadata through GitHub OIDC, and attach both to releases.
• Remove local crates.io patch blockers by publishing renamed vendored dependencies in dependency order.
• Add WinGet manifests and live-schema/checksum validation; upstream WinGet PR is open separately.
• Add focused integration pages for Codex, Claude Code, Cursor, Gemini CLI, OpenCode, and MCP.
• Record upstream patch status and draft contributions for CandleEmbed and USearch.

Validation

• ./test.sh: Rust fmt/clippy/tests, 639 library tests, integration suites, web typecheck/tests/build, 147 Python tests
• cargo check --locked --all-targets
• Standalone package verification for hf-hub, USearch, and tree-sitter Haskell; root dependency package ordering validated
• Codex plugin isolated install and version check
• Claude plugin isolated local install and version check
• Plugin, skill, marketplace, HTML, workflow, and WinGet schema validators
• MCPB extraction validation, native MCP initialize handshake, and MCP Registry publisher validation
• Desktop and mobile integration-page smoke checks

Distribution follow-up

• First crates.io bootstrap requires repository secret CRATES_IO_TOKEN; later runs can use trusted publishing OIDC.
• WinGet PR requires contributor CLA reply before validation continues.

Upstream drafts

• CandleEmbed batch and accelerator support: Add batched inference and accelerator support ShelbyJenkins/candle_embed#2
• USearch reserve sizing: Fix: Keep reserve capacity exact and monotonic unum-cloud/USearch#777
• USearch Windows CRT linkage: Fix: Respect Cargo-selected Windows CRT unum-cloud/USearch#778

Tests/checks run and results.

• ./test.sh passed. Included cargo fmt -- --check, shellcheck, cargo clippy --all-targets --locked -- -D warnings, pnpm -C web install --frozen-lockfile, pnpm -C web check, pnpm -C web build, git diff --exit-code -- web/dist, cargo test --lib --bins --tests --locked, and python3 -m unittest discover -s tests -p 'test_*.py' -v.
• Local test totals: Rust suites passed, including 639 unit/integration tests plus stress harness 10 passed, 11 ignored, 0 failed; Python suites 147 passed.
• cargo build --locked --release passed.
• uv run scripts/validate_winget.py packaging/winget/BrunoVolpato.ivygrep/1.2.5 passed.
• Exploratory packaging smoke: cargo package --allow-dirty --no-verify passed for vendor/hf-hub, vendor/usearch, and vendor/tree-sitter-haskell. Root crate and vendor/candle_embed remain pre-publication blocked on unpublished renamed crates and were treated as non-gating release-sequencing checks, not PR blockers.
• GitHub checks passed: 16 successful, 2 skipped, 0 pending.

Fixes committed/pushed, if any.

• None.

Correction to prior verification record:

• Full local ./test.sh ran on pre-refresh head fd5cbe8eee9fd4d6d596a1379cdeb165065bb88c.
• Final head adds merged, independently validated PRs chore(deps): bump the cargo group with 13 updates #191 and chore(deps): bump the github-actions group with 2 updates #190 plus commit 369d706, which refreshes distribution workflow evidence.
• Final-head GitHub CI passed: 16 successful, 2 skipped, 0 pending.
• Final-head local python3 scripts/render_evidence_dashboard.py produced no diff.
• Final-head release/evidence/distribution tests passed: 23 tests.
• Final-head CLI help snapshot passed: 1 test.

No unverified local-full-suite claim should be inferred for final head beyond these checks and GitHub CI.
