v1.1.0: DB path fix, API hardening, tests, CI, changelog, README repair

[3D3Q3]

Summary

Applies the reviewed v1.1.0 changes from the external review session.

Fixed

• Dedupe DB path (critical): seen_ids.sqlite was created in whatever directory the user ran from, breaking duplicate detection across directories. It now lives at ~/.chtext/seen_ids.sqlite, with automatic one-time migration of a legacy CWD database.
• API _call hardening: network errors (requests.RequestException), non-2xx responses (raise_for_status), and non-JSON responses (rate limit/outage) are now wrapped in CtextAPIError instead of raising raw tracebacks.
• Bare except: in the cmd_browse chapter-title loop → except Exception: so KeyboardInterrupt isn't swallowed.
• Windows encoding: replaced the import-time sys.stdout/sys.stderr swap (which mutated global state for library importers) with a _configure_console_encoding() call at the start of main() using stream.reconfigure().
• README: repaired broken markdown-links-in-code-blocks in install commands, fixed LICENSE links, removed a stray 4-backtick fence.

Added

• tests/test_chtext.py — 21 offline tests covering CTextAPI, StateTracker (including a regression test that the default DB path is not the CWD), _extract_short_segments, and Config.
• .github/workflows/ci.yml — lint (ruff) + test matrix on Python 3.9–3.13.
• CHANGELOG.md (Keep a Changelog format).
• README badges and a Known Limitations section.

Changed

• Version is now dynamic ([tool.setuptools.dynamic] reading chtext.cli.__version__ = 1.1.0); build requires setuptools>=77 for the PEP 639 SPDX license string.
• Minimum Python raised from 3.8 to 3.9. The first CI run showed setuptools>=77 cannot install on Python 3.8 (its floor is 3.9), so the 3.8 job failed at build-dependency resolution. Python 3.8 has been EOL since October 2024, so 3.8 was dropped rather than reverting to legacy license metadata.
• Lint cleanup (unused imports, placeholder-less f-strings) and ruff config in pyproject.toml.

Verification (all run on this branch)

• ruff check src/ tests/ — clean
• python -m pytest tests/ -q — 21 passed
• python -m build — produces chtext-1.1.0 sdist + wheel
• Runtime smoke test: chtext generate from /tmp works, no seen_ids.sqlite created in /tmp, DB present at ~/.chtext/seen_ids.sqlite

Release notes

After merge: confirm CI is green, then create a GitHub release tagged v1.1.0 to trigger the publish workflow. Note that PyPI trusted publishing must be registered for 3D3Q3/chtext and a pypi environment must exist in repo settings, or the publish job will fail on OIDC.
