feat: bound repository context size in load_repo_context (#24)

Addressed Issues:

Fixes #24

Screenshots/Recordings:

N/A

Additional Notes:

• Introduced _read_capped_file helper with DEFAULT_MAX_FILE_CHARS = 2000 and TRUNCATION_MARKER = "\n... (truncated)" to bound individual markdown files (operational data, architecture, core context, instructions, skills, and README).
• Introduced _append_bounded_section enforcing DEFAULT_MAX_TOTAL_CONTEXT_CHARS = 12000 across all assembled sections, ensuring the joined repository context never exceeds the LLM prompt budget.
• Replaced ad-hoc README truncation with the shared _read_capped_file strategy for consistency across all markdown context sources.
• Preserved all existing intent-based file routing, keyword matching, and error logging behavior.
• Added dedicated test suite scripts/test_bounded_context.py covering capped reads, section budget bounds, mock repo bounds, and real repo context loading (23/23 assertions passing).
• Verified existing scripts/test_link_and_issue_features.py (56/56 passing) and scripts/routing_smoke_check.py.
