feat(pdftract-59zz): implement MCP bearer token ingress channels and TH-03 enforcement
Implements secure MCP bearer-token ingress channels and TH-03 startup abort
enforcement per plan lines 874, 915-921, 922-924.
## Changes
- Add `--auth-token-file PATH` flag (RECOMMENDED channel)
- Add `PDFTRACT_MCP_TOKEN` env var support
- Reject `--auth-token VALUE` unless `PDFTRACT_INSECURE_CLI_TOKEN=1`
- Enforce TH-03: require token for non-loopback bind addresses (exit 78)
- Loopback exemption for 127.0.0.0/8 and ::1/128
## Files
- crates/pdftract-cli/src/mcp/auth.rs: Token resolution with priority order
- crates/pdftract-cli/src/mcp/bind.rs: TH-03 bind security check
- crates/pdftract-cli/src/mcp/server.rs: MCP server entry point
- crates/pdftract-cli/src/mcp/mod.rs: Module exports
- crates/pdftract-cli/src/main.rs: CLI arguments
- crates/pdftract-cli/Cargo.toml: Add secrecy, tempfile dependencies
## Acceptance Criteria
- ✅ --auth-token-file PATH flag implemented
- ✅ PDFTRACT_MCP_TOKEN env var resolved
- ✅ --auth-token VALUE rejected (exit 64) unless PDFTRACT_INSECURE_CLI_TOKEN=1
- ✅ mcp --bind ADDR with non-loopback ADDR and no token: aborts with exit 78
- ✅ mcp --bind ADDR with loopback ADDR and no token: succeeds
- ✅ mcp --bind ADDR with token: succeeds regardless of address
- ⏸️ Inspector token: Phase 7.9 (not yet implemented)
- ⏸️ TH-03 test: separate bead
