Fixes a bug where adding a second MCP server caused the first to disappear
from the list view, and any args containing YAML reserved characters (e.g.
"@modelcontextprotocol/server-fetch") corrupted the config file.
Three root causes in HermesFileService MCP YAML patching:
1. extractMCPBlock extended through trailing comments to EOF when
mcp_servers was the last top-level key in config.yaml. Trailing
comments became part of the "block", so subsequent inserts landed
at end-of-file rather than inside the entry.
2. patchMCPServerField's entry boundary similarly absorbed trailing
blanks/comments, making the entry "own" everything until the next
sibling — or until EOF for the last entry.
3. yamlScalar did not quote values starting with YAML reserved
indicators (@ * & ? | > ! % , [ ] { } < ` ' "). Args like
"@modelcontextprotocol/server-fetch" were written bare, producing
invalid YAML that broke subsequent reads/writes.
Fix: trim trailing blanks/comments off both the block and the entry
in the locator/extractor; quote any scalar starting with a reserved
first character.
Bumps version to 1.5.7 (build 9). Includes signed Universal + ARM64
binaries.
Note: users with an already-corrupted ~/.hermes/config.yaml from the
1.5.6 bug should manually clean up their mcp_servers block (delete the
orphan args at end of file) before upgrading. New writes will be clean.
The first 1.5.6 zips contained `linker-signed` bundles with no Sealed
Resources, plus a stray nested scarf.app from a case-insensitive cp.
macOS Gatekeeper rejected the ARM64 download as "damaged"; the
Universal one ran only because the user had already trusted it.
Now both bundles are properly ad-hoc-signed (`Sealed Resources
version=2`) with the hardened runtime preserved. Sizes dropped
significantly (Universal 33MB→16MB, ARM64 27MB→13MB) because the
nested junk is gone.

Includes the MCP Servers management UI shipped in 219bca2:
- Add via curated presets (GitHub, Linear, Notion, Sentry, Stripe, …)
or fully custom (stdio command + args, or HTTP URL with bearer auth)
- Per-server detail view: enable/disable, env + headers editor,
tool include/exclude filters, resources/prompts toggles, request
and connect timeouts, OAuth token detection + clearing
- One-click "Test Connection" runs `hermes mcp test` and surfaces
the discovered tool list
- Gateway-restart banner after config changes that need a reload
README updated with the MCP Servers section, the new MCPServers/
feature module entry, and the `hermes mcp` + `mcp-tokens/` entries
in the Data Sources table.
