feat: execute bounded local Hookify rules in lifecycle hooks

Carry forward PR #3055 at 92f53c4c onto ef648e01, preserving contributor attribution and current main. Focused maintainer fixes reuse shared input ceilings, preserve late root context through outer bootstrap, bound frontmatter before immutable parsing, and assert real oversized input in the limits workflow.

 ## Hook System Overview
 Hookify creates rule files that integrate with Claude Code's hook system to prevent unwanted behaviors.
 ECC's built-in runtime loads these rules automatically while plugin hooks are
 enabled; installing a separate Hookify plugin is not required.
 ### Event Types
 - `bash`: triggers on Bash tool use and matches command patterns
 - `file`: triggers on Write/Edit tool use and matches file paths
- `stop`: triggers when a session ends
+- `stop`: triggers after each Claude response
 - `prompt`: triggers on user message submission and matches input patterns
 - `all`: triggers on all events
@@ -44,3 +46,14 @@ Supports multiple lines.
 - for `bash`, match against the full command string
 - for `file`, match against the file path
 - test patterns before deploying
 - avoid nested quantifiers such as `(a+)+`; the runtime rejects unsafe regexes
 - every regex evaluation also has a 25 ms hard timeout
 - malformed or oversized rules fail open with a diagnostic so one bad local rule cannot disable all hooks
 - Git-tracked local rules require explicit `ECC_HOOKIFY_ALLOW_TRACKED=1` approval
 ### Action Behavior
 - `warn` adds the rule message to Claude's context and allows processing to continue
 - `block` denies matching shell/file actions before execution
 - `block` on prompt, post-tool, or stop events uses that event's structured block decision
 - stop rules are skipped when `stop_hook_active` is already true to prevent loops

 ### Hookify Rule Runtime
 ECC loads enabled `.claude/hookify.*.local.md` files directly; no separate
 Hookify plugin or Python runtime is required. Rules support `bash`, `file`,
 `prompt`, `stop`, and `all` events, plus either a simple regex `pattern` or an
 AND-combined `conditions` list. `warn` adds visible context for Claude while
 allowing the action. `block` denies a matching `PreToolUse` call and uses the
 event's blocking decision contract for prompt, post-tool, and stop events.
 Rule loading is project-scoped and bounded. Symlinked, oversized, malformed,
 or unsafe-regex rule files are skipped with a diagnostic instead of breaking
 the entire hook chain. Every regex evaluation also has a 25 ms hard timeout.
 Stop rules ignore `stop_hook_active: true` to avoid continuation loops.
 Files tracked by Git are disabled by default because opening a repository must
 not activate repository-authored instructions. Locally created, gitignored
 rules continue to work automatically. To review and explicitly trust tracked
 rules, set `ECC_HOOKIFY_ALLOW_TRACKED=1`; messages are still labeled as
 untrusted local rule data when passed to Claude.

 ## Overview
 ECC evaluates project-local Hookify rules with its built-in Node runtime. No
 separate Hookify plugin or Python installation is required when ECC hooks are
 enabled.
 Hookify rules are markdown files with YAML frontmatter that define patterns to watch for and messages to show when those patterns match. Rules are stored in `.claude/hookify.{rule-name}.local.md` files.
 ## Rule File Format
@@ -101,6 +105,23 @@ Match user prompt content for workflow enforcement.
 python3 -c "import re; print(re.search(r'your_pattern', 'test text'))"
 ```
 Avoid nested quantifiers such as `(a+)+`. The runtime rejects patterns with
 common catastrophic-backtracking shapes because rules run synchronously in the
 hook path, and every regex evaluation has a 25 ms hard timeout. Invalid,
 symlinked, or oversized local rules fail open and emit a
 diagnostic without disabling other Hookify rules.
 Git-tracked local rules are disabled by default. Set
 `ECC_HOOKIFY_ALLOW_TRACKED=1` only after reviewing those files; ordinary
 gitignored rules created locally remain active without that override.
 ## Runtime Behavior
 - `warn` injects the message as event-specific additional context and does not block.
 - `block` denies matching Bash, PowerShell, Write, Edit, or MultiEdit calls before execution.
 - On prompt, post-tool, and stop events, `block` uses Claude Code's structured block decision.
 - Stop rules skip recursive `stop_hook_active` events to prevent infinite continuation loops.
 ## File Organization
 - **Location**: `.claude/` directory in project root
