Subject: [PATCH 1/6] feat: Add Telnet support to gnetcli server
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add StreamerType enum (ssh/telnet) to proto
- Add streamer_type field to HostParams
- Update server.go to select SSH or Telnet streamer based on streamer_type
- Add WithPort option to telnet streamer
- Update Python SDK with streamer_type support

Subject: [PATCH 2/6] fix: Replace proto symlink with actual files for pip
 install
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Remove symlink to pkg/server/proto
- Copy proto files directly to gnetclisdk/proto/
- Add __init__.py files for proper package structure
- Update setup.py to use find_packages()

Subject: [PATCH 5/6] Fix telnet pager handling to preserve newlines and
 prevent text corruption
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit fixes two issues with telnet pager handling that caused
configuration lines to be corrupted when fetching device configs:

1. **Newline preservation**: The pager pattern `\r\n --More--` was
   consuming the `\r\n` that should separate configuration lines. Now
   we restore the `\r\n` after the pager is answered to prevent lines
   from merging together.

2. **Backspace clearing sequence stripping**: After answering the pager,
   Cisco devices send a sequence of backspaces, spaces, and backspaces
   to clear the "--More--" prompt from the terminal. Since we already
   remove the pager pattern from the buffer, these control sequences
   would incorrectly delete real content. Added stripPagerClearingSequence()
   to detect and remove these clearing patterns.

Example of the issue fixed:
- Before: "description BG_W451-Obrenov no switchport" (truncated & merged)
- After:  "description BG_W451-ObrenovacStocnjak" + "no switchport" (separate lines)

Changes:
- Added stripPagerClearingSequence() function to detect and remove
  backspace clearing patterns (\b{n} + spaces + \b{n})
- Added pagerAnswered flag to track when to strip clearing sequences
- Restore \r\n in pager handling to preserve line breaks
- Added comprehensive tests for pager newline preservation
- Added tests for stripPagerClearingSequence() function

Related to earlier fix for leading backspace handling in parser.go
