• refactor(coding-agent): fix compaction for branched sessions, consolidate hook context types

  Compaction API:
  - prepareCompaction() now takes (pathEntries, settings) only
  - CompactionPreparation restructured: removed cutPoint/messagesToKeep/boundaryStart, added turnPrefixMessages/isSplitTurn/previousSummary/fileOps/settings
  - compact() now takes (preparation, model, apiKey, customInstructions?, signal?)
  - Fixed token overflow by using getPath() instead of getEntries()
  
  Hook types:
  - HookEventContext renamed to HookContext
  - HookCommandContext removed, RegisteredCommand.handler takes (args, ctx)
  - HookContext now includes model field
  - SessionBeforeCompactEvent: removed previousCompactions/model, added branchEntries
  - SessionBeforeTreeEvent: removed model (use ctx.model)
  - HookRunner.initialize() added for modes to set up callbacks

• Extract shared compaction/branch-summarization utils

  - New utils.ts with shared functions:
    - FileOperations type and createFileOps()
    - extractFileOpsFromMessage()
    - computeFileLists()
    - formatFileOperations()
    - serializeConversation()
    - SUMMARIZATION_SYSTEM_PROMPT
  
  - branch-summarization.ts now uses:
    - Serialization approach (conversation as text, not LLM messages)
    - completeSimple with system prompt
    - Shared utility functions

• Use convertToLlm before serializing, include thinking, remove truncation

  - serializeConversation now takes Message[] (after convertToLlm)
  - Handles all custom message types via convertToLlm
  - Includes thinking blocks as [Assistant thinking]
  - Removes truncation of tool args and results (already token-budgeted)

• Serialize conversation to text for summarization

  Instead of passing conversation as LLM messages (which makes the model
  try to continue it), serialize to text wrapped in <conversation> tags.
  
  - serializeConversation() formats messages as [User]/[Assistant]/[Tool result]
  - Tool calls shown as function(args) format
  - Tool results truncated to prevent bloat
  - Conversation wrapped in <conversation> tags in the prompt

• Add system prompt to compaction summarization

  - SUMMARIZATION_SYSTEM_PROMPT explains the task clearly
  - Tells model to NOT continue conversation, ONLY output summary
  - Updated prompts to reference 'messages above' for clarity
  - Pass systemPrompt to completeSimple

• Add file tracking and iterative summary merging to compaction

  - CompactionDetails type with readFiles/modifiedFiles
  - extractFileOperations collects from tool calls and previous compaction details
  - UPDATE_SUMMARIZATION_PROMPT for merging with previous summary
  - generateSummary now accepts previousSummary for iterative updates
  - compact() extracts files, passes previousSummary, returns details
  - Only merges from !fromHook compaction entries (backward compatible)

• Use structured output format for compaction and branch summarization

  Both now use consistent sections:
  - Goal
  - Constraints & Preferences
  - Progress (Done/In Progress/Blocked)
  - Key Decisions
  - Next Steps
  - Critical Context (compaction only)
  
  Prompts instruct LLM to use EXACT format and preserve file paths/function names.

• Refactor: move compaction code to src/core/compaction/

  - Move compaction.ts to src/core/compaction/compaction.ts
  - Extract branch summarization to src/core/compaction/branch-summarization.ts
  - Add index.ts to re-export all compaction utilities
  - Update all imports across the codebase
