fix: Windows/Termux compatibility, comic theme fonts, and UI fixes (#630)

* fix: comprehensive Windows compatibility and gateway management improvements

This commit addresses multiple Windows compatibility issues and improves
gateway management across all platforms.

## Windows Compatibility Fixes
- Add hermes-path.ts with cross-platform Hermes home/bin detection
- Fix Windows native installation paths (%LOCALAPPDATA%\hermes)
- Update terminal.ts to use PowerShell instead of /bin/bash on Windows
- Fix upload.ts path construction to use path.join() for cross-platform paths
- Fix download.ts to use isAbsolute() for Windows absolute path detection
- Update auth.ts to skip file mode 0o600 on Windows (unsupported)
- Add nodemon.json for cross-platform environment variable handling

## Gateway Management Improvements
- Simplify gateway startup: all platforms use 'run' mode uniformly
- Remove complex init system detection and platform-specific code paths
- Improve PID file validation: use health check instead of port detection
- Remove getPortByPid() method (too complex and error-prone)
- Remove checkPortAvailable() TCP bind test (TIME_WAIT false positives)
- Trust gateway --replace flag to handle real port conflicts
- Add smart PID validation: check if stale process via health check
- Fix port allocation to avoid incrementing when gateway restarts
- Add allocatedPorts.clear() on each startAll() call
- Add clearPidFile() method to clean up stale PID files

## Process Management
- Remove detached:true and unref() from gateway spawn
- Gateway processes now follow parent process lifecycle
- Add process reference storage in ManagedGateway interface
- Improve shutdown logic: call gatewayManager.stopAll() before exit
- Fix Windows process killing: use process.kill(pid) for Windows
- Remove PowerShell command for lock file cleanup (use Node.js fs.unlinkSync)

## Frontend Theme Fixes
- Fix main.ts localStorage key mismatch (hermes_theme → hermes_brightness)
- Add inline script in index.html to prevent FOUC (Flash of Unstyled Content)
- Apply theme classes before Vue mount to avoid visual glitches

## Developer Experience
- Fix nodemon windows-kill popup on Windows by removing signal config
- Add delay and environment variables to nodemon.json
- Add windowsHide: true to all child process spawns

## Breaking Changes
- Gateway management now exclusively uses 'run' mode on all platforms
- systemd/launchd integration removed (use --replace flag instead)

This fix ensures hermes-web-ui works correctly on Windows native
installations while maintaining compatibility with Linux/macOS/WSL2.

* Fix gateway lifecycle port handling

* fix: comprehensive Windows compatibility and gateway management improvements

- Simplified hermes CLI binary resolution logic
- Fixed Windows line ending compatibility in profile list parsing
- Migrated gateway restart logic from CLI to GatewayManager
- Added gateway restart to updateCredentials method
- Removed unnecessary gateway restarts from provider operations
- Fixed configuration preservation when switching profiles
- Added nodemon quiet mode and legacy watch to reduce Windows popups

* revert: change back to nodemon due to tsx compatibility issues

- tsx has compatibility issues with Koa generator functions
- Restored nodemon with simplified configuration
- Added cross-env package for future Windows environment variable needs

* feat: replace nodemon with ts-node-dev to eliminate Windows popup windows

- Installed ts-node-dev as nodemon replacement
- ts-node-dev has better Windows compatibility without console popups
- Supports respawning, inspector debugging, and TypeScript compilation
- Uses cross-env for Windows environment variable support
- Removed nodemon.json configuration file (no longer needed)

Benefits:
- No more Windows console popup windows during development
- Faster restart times compared to nodemon
- Built-in TypeScript compilation without ts-node overhead

* fix: improve log parsing and Windows compatibility for agent/error logs

- Fixed Pino JSON log parsing bug where logger field incorrectly used obj.msg
- Changed logger field to use obj.name to properly display log source
- Added Windows line ending support (\r\n) for log file listing
- Added support for 'error' log type in addition to 'errors'
- Improved error message extraction from obj.err when available

This fixes the missing agent and error logs issue on Windows.

* Fix gateway health checks and shutdown ownership

* Refine auth lock window and dev shutdown

* fix: improve Hermes plugin discovery on Windows by fixing Python path resolution

- Added support for Windows venv Scripts directory structure
- Fixed Python executable path detection for hermes.exe in venv/Scripts/
- Added Windows LOCALAPPDATA hermes-agent directory to search paths
- Improved cross-platform compatibility for plugin discovery

This fixes the "No module named 'hermes_cli'" error on Windows by correctly
locating the Python virtual environment that contains the Hermes modules.

* refactor: improve cross-platform compatibility for Hermes plugin discovery

- Added platform detection to only add Windows-specific paths on Windows
- Prevents potential issues on Unix/Linux/macOS systems
- Ensures LOCALAPPDATA path is only used when available on Windows
- Maintains existing behavior for all platforms

This makes the Windows plugin discovery fix safer for cross-platform usage.

* chore: remove unused development dependencies

- Removed nodemon (replaced by ts-node-dev)
- Removed tsx (had compatibility issues with Koa)
- Removed nodemon.json configuration file
- Cleaned up development tools to only what's actually used

This reduces dependency size and eliminates the windows-kill popup
source that was part of nodemon.

* chore: remove memory system files

- Removed MEMORY.md index file
- Removed memory/ directory and windows-compatibility.md
- Cleaned up unused memory persistence system

* fix: resolve TypeScript compilation error in plugins.ts

- Added type assertion 'as string[]' after filter(Boolean)
- Fixes TS2769 error: No overload matches this call
- Ensures type compatibility with hasHermesPluginModule function

* fix: comprehensive Windows compatibility and gateway management improvements

- Fix gateway detection after nodemon restart by adding health check-based detection
- Prevent port conflicts by detecting already-running gateways without PID files
- Switch to serial gateway startup to avoid lock file race conditions
- Return to nodemon from ts-node-dev for development stability
- Always stop gateways on shutdown to prevent orphan processes
- Prevent project root config files from being committed to git
- Fix syntax issues in plugins.ts

Resolves issues where default profile gateway failed to start after
nodemon restart and gateways were incorrectly marked as stopped
despite running on correct ports.

* feat: comic theme multilingual fonts, sidebar collapse fix, plugin discovery for Termux, and cron history

- Add Chinese (ZCOOL KuaiLe), Japanese (Zen Maru Gothic), Korean (Gaegu) handwritten fonts for Comic theme
- Fix collapsed sidebar: hide language switch, stack theme icons vertically
- Add hermes shebang parsing as fallback Python discovery for Termux
- Remove cron source filter from history sessions
- Add 0.5.17 changelog entries for all 8 locales

* fix: tolerate duplicate YAML keys in config parsing (closes #628)

Add `{ json: true }` to all 7 `yaml.load()` calls so duplicated mapping
keys (e.g. multiple `mcp_servers:` blocks) no longer crash the API.

* fix: gateway ownership check requires PID file to prevent cross-profile port hijacking

Remove fallback that assumed ownership of healthy gateways without PID
verification. Now only claims a gateway if PID file exists and process
is alive, preventing one profile from hijacking another's port.
