feat: Add configurable timeouts for HTTP requests

This commit introduces configurable timeouts for HTTP requests made by the `collect` commands.

Key changes:
- Created a new `pkg/httpclient` package with a `NewClient` function that returns an `http.Client` with configurable timeouts for total, connect, TLS, and header stages.
- Added `--timeout`, `--connect-timeout`, `--tls-timeout`, and `--header-timeout` persistent flags to the `collect` command, making them available to all its subcommands.
- Refactored the `pkg/website`, `pkg/pwa`, and `pkg/github` packages to accept and use a custom `http.Client`, allowing the timeout configurations to be injected.
- Updated the `collect website`, `collect pwa`, and `collect github repos` commands to create a configured HTTP client based on the new flags and pass it to the respective packages.
- Added unit tests for the `pkg/httpclient` package to verify correct timeout configuration.
- Fixed all test and build failures that resulted from the refactoring.
- Addressed an unrelated build failure by creating a placeholder file (`pkg/player/frontend/demo-track.smsg`).

This work addresses the initial requirement for configurable timeouts via command-line flags. Further work is needed to implement per-domain overrides from a configuration file and idle timeouts for large file downloads.
