chore: bump version to 0.1.9

[echobt]

Summary

• Fix terminal startup and cleanup: own restoration before fallible initialization, clear stale cells without erasing scrollback, and attempt all cleanup steps even after output failures.
• Use the shared lifecycle for trust/login preflight screens and preserve the configured alternate-screen preference.
• Refresh the README with a generated green CLI/macOS-styled desktop animation and moving pointer, explicitly labeled as an offline composite; add its runnable validation check.
• Prepare stable 0.1.9 across CLI/workspace/SDK versions, lockfile, generated API contract, and changelog. No external dependency upgrades; stream-json protocol stays unchanged.

Test plan

• cargo fmt --all -- --check and ./scripts/clippy.sh
• cargo test --workspace: 6,415 passed, 0 failed (211 existing ignored)
• Explicit TUI package suite: 1,672 passed, 0 failed (132 existing ignored)
• cargo audit, version consistency, cargo-machete, release-age and schema freshness
• Source policy against 8672e672a2003954a8aaa1752a84cdbda68b4725: 0 regressions, 0 policy failures; 159 existing findings retained
• Readiness Python tests: 50 passed, 2 skipped; real local QA: all 15 cases passed
• SDK: 20 tests passed; generated-demo pixel, pointer, frame-count and size checks passed
• Six real-PTY cases: default, CLI inline flag and config inline mode at 40×12 and 120×40. Clean trust/login frames, exit 0, exact termios restoration, shell echo, preserved offscreen history, no cursor-position query or scrollback erase
• Changed-line coverage reviewed: no modified production lines in the enforced CLI/app-server/common scope; instrumented local coverage not run, CI gate required

Attestation (required)

• Security reviewed — auth, exec/sandbox, paths, network egress, and secret handling reviewed; this diff changes terminal lifecycle and release/demo metadata, not authentication policy.
• Product-facing errors — no new provider/transport errors exposed.
• TUI verified — build, physical-backend/headless regressions and all six real-PTY cases passed on the final implementation.
• Tests added — startup/cleanup failure and inline preference checks, preflight headless buffer checks, generated-demo assertions. No mock-success.
• No secrets — no credentials, keyring dumps, or .env files included.

Risk

Terminal modes and first-run screens change. Real terminal validation runs on Linux; native macOS/Windows interaction and authenticated model turns are not claimed. The GIF is generated, not a desktop recording.

Release is limited to CLI binaries/installers/manifests. Squash commit must contain chore: bump version to 0.1.9 so the existing version workflow tags this release.

@greptileai review

Please review latest commit 87f8a18. Both documentation findings are fixed. It also removes the redundant startup cursor-position query identified by real-PTY testing. All six terminal cases and final local Rust/policy gates pass.
