feat: add ascent report command (#5)

* docs: add design document for ascent report command

Adds comprehensive design for new 'peakbagger ascent show' command
that retrieves detailed ascent reports from PeakBagger.com.

Design covers:
- Command structure and CLI interface
- Data model extensions to Ascent model
- HTML parsing strategy for ascent detail pages
- Output formatting (text and JSON)
- Testing approach with real PeakBagger data

* feat: extend Ascent model with fields for detailed reports

Add optional fields to Ascent model for ascent detail pages:
- Ascent metadata (type, peak info, location, elevation)
- GPX-derived metrics (gain, distance, duration)
- Trip report content (text, external URL)

Update to_dict() to serialize new fields conditionally.

* feat: add parser for ascent detail pages

Add parse_ascent_detail() method to extract:
- Basic ascent metadata (date, type, climber, peak)
- Location and elevation information
- GPX-derived metrics (gain, distance, duration)
- Full trip report text and external URLs

Handles various date formats and missing fields gracefully.

* refactor: clean up imports in formatters.py

- Move Text import to top-level imports
- Remove redundant json and Table imports in format_ascent_detail()
- Use _print_json() helper instead of manual JSON serialization

All tests passing. No functional changes.

* feat: add 'peakbagger ascent show' command

Add new command to retrieve detailed ascent reports:
- New 'ascent' command group
- 'show' subcommand accepting ascent ID
- Supports --format (text/json) and --rate-limit options
- Fetches from /climber/ascent.aspx endpoint
- Displays metadata, GPX metrics, and trip report

Examples:
  peakbagger ascent show 12963
  peakbagger ascent show 12963 --format json

* chore: fix linting and formatting issues

- Rename show function to show_ascent in ascent command to avoid
  ruff F811 redefinition error
- Apply ruff formatting to models.py for long Field definition
- All tests pass, no functional changes

* test: remove tests that depended on temporary files

Remove parser tests that relied on /tmp HTML files. These were
development artifacts. The VCR-based integration tests provide
adequate coverage for the ascent show command and parsing logic.

All tests now pass cleanly.
