feat(security): security hardening, proxy support, and GL045 HTTP include warning
Security fixes:
- Path traversal guard in include: local: — paths with ../ that escape
  the repo root are rejected instead of reading arbitrary host files
- HTTP timeout (30 s) on all fetcher requests to prevent indefinite hangs
- Response size cap (10 MiB) via io.LimitReader to prevent memory exhaustion
- Cache directory and file permissions tightened to 0700/0600
- LSP Content-Length cap (64 MiB) to guard against DoS from a malicious client

New feature:
- --proxy flag on check, graph, and lsp subcommands; also proxy: key in
  .glint.yml; overrides system HTTP_PROXY / HTTPS_PROXY env vars when set;
  cmdGraph and cmdLSP now also load .glint.yml for proxy/token/url fallbacks

New lint rule:
- GL045 (Warning): include: remote: using plain http:// instead of https://

Reads JSON-RPC 2.0 messages from stdin and writes responses to stdout using
the standard Content-Length framing. Connect with any LSP client (VS Code,
Neovim, Emacs, etc.).
Usage: glint lsp [OPTIONS]
Options:
--token <TOKEN>
GitLab personal access token used for resolving project: and
component: includes. Defaults to GITLAB_TOKEN env var.
--gitlab-url <URL>
GitLab instance URL for resolving remote includes.
[env: CI_SERVER_URL | GITLAB_URL] [default: https://gitlab.com]
--cache-dir <DIR>
Cache directory for fetched remote includes. Defaults to
~/.cache/glint so subsequent opens are served from cache.
--offline
Do not make any network calls; resolve only local includes.
Implies --cache-dir default (~/.cache/glint) when not set.
--proxy <URL>
HTTP proxy URL for remote includes and GitLab API calls
(e.g. http://proxy:8080). Overrides system proxy env vars
(HTTP_PROXY / HTTPS_PROXY). Also configurable via proxy: in
.glint.yml.
-h, --help
Print help
Examples:
glint lsp
glint lsp --token glpat-xxxx --cache-dir ~/.cache/glint
glint lsp --offline
glint lsp --proxy http://proxy.example.com:8080
